CBSE Class 9 Annual Exam 2021

The Central Board of Secondary Education (CBSE) has suggested all its schools to hold offline examinations for Classes 9th and 11th and start the next academic session (2021-2022) by April 1 this year. All the schools have been asked to make arrangements for the exams strictly following the Covid-19 protocols. Many CBSE schools across the country have resumed in-person classes to prepare students for the offline exam. However, many students and their parents have been constantly requesting schools to organise online examinations due to the risk of infection with the coronavirus. Students claim that online classes are not sufficient to write the examination in offline mode. 

If we talk about the educators’ opinions then all of them are in favour of the offline exam as they find it the only way to conduct a fair assessment of the students’ performance. In online mode, invigilation cannot be done as it is done in the examination hall. Moreover, there may be chances of the poor network that will disturb the whole examination process including publishing question papers and uploading of answers on time. Therefore chances are less for the CBSE class 9 and class 11 exams to be conducted in online mode. Therefore, all the students should get ready with their pens and pencils to write the offline exam at their respective schools.

We have put up here a few important tips for CBSE Class 9 students that will help them write their offline exam appropriately and secure the desired marks. You can also check here some of the very important resources that will make your exam preparations much easy and organised.

1. Learn by writing down with pen and paper

Do not simply read and mug up the things. Instead, practice by writing down the complex questions in a notebook or sheet. While writing, make sure to pay attention to your speed. In the offline exam, you would need to write subjective answers that may take a lot of time if you had not practiced well before the exam.

2. Solve practice papers and NCERT questions

In the last month before the exam, solve several questions in the form of practice tests. Attempt all the exercise questions given the NCERT Books. You need to be well-versed with all important topics and master confidence over the same with practice and revision. Solving different types of questions will boost your confidence and make you prepared for writing your exam perfectly. You may try some practice tests by Jagran Josh:

Knowledge and confidence play a big role in determining your performance in the exam. It makes you better at time management and increases the accuracy of your answers in the examination hall.

3. Do what you did in your previous classes’ exams

 Offline exams are not a new thing for all students. All of you have been taking exams in the same mode in your previous classes. So, do whatever you did at that time. Follow the same rules for last minute revision. Choose the sequence of questions that suits you the best while writing the exam, i.e., whether you like to attempt the long questions first or the shorter ones. Do all that you did in your previous years’ exams for writing a smooth exam and keeping the stress away.

4. Save 10-20 minutes time to revise your answers

Do not forget to keep a margin of 10-20 minutes for reading through the entire answer sheet after finish your paper. This will help you review your answers and eliminate errors (if any). It will also act as a double check if you have missed any question(s). While reading any answer some important points or facts may come to your mind which you may add to that particular answer to make it more informative. Reviewing the paper will boost your confidence towards your performance and remove the post-exam anxiety.

5. Do not hesitate to seek support

It is the only way to remove any exam related stress and anxiety. You have your parents/elders at home and teachers in the school to assist you with all your doubts and problems. Do not miss any opportunity to take away from their experience in handling such tough situations. Discuss your problem with them to remove all your doubts whether they are related to academics or general.

Dear students, we understand your concern that writing the exam offline after reading the course online all through the year is not going to be that simple. It is obvious for you to over think about your expectations and results. But, everyone is adjusting and trying to fit in the new normal. So, you also need to have the courage to face the challenge with full confidence and achieve success in your upcoming CBSE Class 9 Annual Exam 2021.

3. Prepare a chapter-wise list of formulas

Maths is purely based on logic and formulas. So, to score well in Mathematics, all you need is to be good at the formulas and concepts applied in the subject. Maintain a chapter-wise list of all important formulas, theorems and axioms so that you may easily revise them every second or third day.

4. Solve textbook questions

Knowing the formulas on your tips is not going to help you score the desired marks until and unless you know their right application. For this, you have to solve all the textbook questions at least twice. Practice the solved examples as well. This will enable you to solve any type of question by applying suitable formula or reasoning the same with an appropriate theorem or axiom. Solving the textbook questions is also important because most of the questions in the exam are directly asked from the textbook.

 # Prepare Class Room Notes:

In the case of exams conducted by schools, classroom notes play an important role. Teachers often give questions based on what they have taught in the classroom. Students are advised to give priority to NCERT Textbooks & Class Notes while doing preparation. 

The practice is also important to score well in exams. Many students know everything but they are unable to finish the complete paper within time due to lack of practice. So students are advised to solve at least five sample papers.

CBSE 10th Board Exam 2021

Check CBSE Class 10 Science Notes for Chapter 5 – Periodic Classification of Elements for quick revision before Board Exam 2021. These notes are according to the revised CBSE Class 10 Science Syllabus. All the topics have been explained in a simple way. It will take only about 10-15 minutes to revise the whole chapter with the help of these quick revision notes.

Revision Notes for CBSE Class 10 Science Notes for Chapter 5 Periodic Classification of Elements:

Need for classification

It is difficult to study a number of element individually and to know their properties and uses. Therefore, they have been classified into groups on the basis of similarities in their properties. Thus, classification is needed to easily understand the properties of a large number of elements arranged in a group. 

Early attempts at classification of elements

Dobereiner’s Triads

It showed that when the three elements in a triad were written in the order of increasing atomic masses; the atomic mass of the middle element was roughly the average of the atomic masses of the other two elements.

Limitations of Dobereiner’s Triads

Dobereiner’s could identify only three triads from the elements known at that time. Thus, he failed to arrange all the known elements in the form of triads, even having similar properties.

Newland’s Law of Octaves

It states that when elements are placed in order of increasing atomic masses, the physical and chemical properties of every 8th element are similar to that of the first element.

Limitations of Newland’s Law of Octaves

1.Newland’s Law of Octaves was applicable only upto calcium, as after calcium every eighth element did not possess properties similar to that of the first.

2.Properties of the elements which were discovered later did not fit into the Law of Octaves.

3.In a few cases, Newlands adjusted two elements in the same slot to fit them in his table.

4.He also grouped unlike elements under the same slot.

Example: Cobalt and nickel are in the same slot and are placed in the same column as fluorine, chlorine and bromine which have different properties than these elements.

Mendeleev’s Periodic Table

It is based on the fact that the physical and chemical properties of the elements are the periodic functions of their atomic masses. This fact is named as Mendeleev’s Periodic Law.

Also Check: CBSE Class 10 Science Best Study Plan for Board Exam 2021

Achievements of Mendeleev’s Periodic Table

1.This table had gaps to give place for some undiscovered elements. 

2.There was a zero group in the table to accommodate the noble gases.

3.It corrected the atomic masses of certain elements. For example, the atomic mass of beryllium was corrected from 13.5 to 9.

Limitation of Mendeleev’s Periodic Table

1.No fixed position could be given to hydrogen in this Table.

2.It did not explained the position of isotopes.

3.In a few cases the trend of increasing atomic masses was not followed. For example, Cobalt (Co) has higher atomic weights but was placed before Nickel (Ni) in the periodic table.

Modern periodic table

This table is based on the Modern Period Law which states that “The physical and chemical properties of elements are the periodic function of their atomic numbers.”

All The elements in this table were arranged in order of increasing atomic numbers.

Elements in the Modern Periodic Table are arranged in 18 vertical columns called groups and 7 horizontal rows called periods.

Periodicity of elements: The recurrence of properties of the elements, after a certain regular intervals, when they are arranged in the increasing order of their atomic numbers, is called periodicity.

Cause of periodicity: It is due to the repetition of the same outer shell electronic configuration at a certain regular intervals.

The Modern Periodic Table removed various anomalies of Mendeleev‘s Periodic Table:

(a) Position of hydrogen is fixed as it is kept in the group with the elements of same valence electrons.

(b) In the Modern Periodic table elements are arranged in the increasing order of their atomic number, so there was no need to place more than one elements in one slot.

(c) The atomic numbers of cobalt and nickel are 27 and 28 respectively. Hence, cobalt with a lower atomic number is placed before nickel in the modern periodic table.

(d) All isotopes of an element have same atomic number but different atomic masses. Therefore, all the isotopes are placed in the same position in the modern periodic table.

Trends in the Modern Periodic Table

Valency: The valency of an element is determined by the number of valence electrons present in the outermost shell of its atom

→ On moving from left to right in a period, the valency first increases from 1 to 4 and then decreases to 0.

→ On moving from top to bottom in a group, the valency remains same because the number of valence electrons remains the same.

Atomic size: Atomic size is determined by the distance between the centre of the nucleus and the outermost shell of an isolated atom.

→ On moving from left to right in a period,  the atomic size decreases due to the increased effective nuclear charge that pulls the valence electrons closer to the nucleus..

→ On moving from top to bottom in a group, the atomic size increases due to the addition of an extra shell at each step.

Metallic character: It is determined by the tendency of an atom to lose its outermost (valence) electrons. 

→ On moving from left to right in a period,  metallic character of elements decreases because due to the increase in nuclear charge the tendency to lose valence electrons decreases.

→ On moving from top to bottom in a group, metallic character of elements increases due to the increase in atomic size that makes it easy to lose the valence electrons.

Non-metallic character: It is determined by the tendency of an atom to gain electrons. 

→ On moving from left to right in a period,  non-metallic character of elements increases because due to the increase in nuclear charge the tendency to gain the electrons increases.

→ On moving from top to bottom in a group, non-metallic character of elements decreases because due to the increase in atomic size the nuclear pull decreases. Due to this the tendency to gain the electrons decreases.
