Class 8 Chemistry is the second year in which ICSE students learn different subdivisions of Science. The bifurcation was introduced to them in the previous year. Students understand the concept of chemicals, the structure of atoms, and many other fundamental concepts of Chemistry. The chapters introduced in ICSE Class 8 Chemistry are a mixture of new topics that will act as fundamental for secondary school and old topics that have been taught in the previous as an introduction to Chemistry. Chemistry is an interesting subject when studied along with visual representation and real-life experiments that take place in laboratories that are conducted in a controlled environment. All of these together not only make the students grasp the basic components of chemistry but also create awe among students.

What is Chapter in Chemistry for Class 8?

The chapters included in ICSE Class 8 Chemistry are, Matter, Physical and Chemical Changes, Elements Compounds and Mixtures, Atomic Structure, Language of Chemistry, Chemical Reactions, Hydrogen, Water, and Carbon and its Compounds. Let us further discuss in detail what a student of ICSE Class 8 Chemistry will learn in the entire year.

1. Matter

Students will be able to acquire knowledge about the main postulates of the kinetic theory of matter. The chapter contains a detailed explanation of the change of state of matter with respect to the attraction of molecules and intermolecular space. Students will also learn about the law of conservation of mass.

• Worksheet – Revision of Elements, Compounds and Mixtures
• Worksheet – Elements, compounds and mixture – a brief explanation.
• Worksheet – Separation of the components of a mixture
• Worksheet – Emphasis on the principle of separation.

4. Atomic Structure

Students will be able to grasp the fundamental concept of subatomic particles present in an atom: electrons, protons, neutrons. It also includes the description of the nucleus and extranuclear parts which the students will be able to describe by the end of the chapter. The chapter has included atomic number and mass number that is required to calculate various empirical formulas in higher classes.

• Worksheet – Fundamental subatomic particles in an atom: electrons, protons, neutrons
• Worksheet – Nucleus and extra nuclear parts
• Worksheet – Atomic number and mass number.

5. Language of Chemistry

Language of Chemistry is one of the important chapters for ICSE Class 8 Chemistry. It contains symbols of elements that must be learnt by the students to understand complex equations. The chapter comprises formulae of compounds. It is then followed by the inclusion of chemical equations (from word equations). The students will also find the Law of conservation of mass. Balancing simple equations are also included.  After being able to balance simple equations students can relate the law to the balancing of simple equations. The chapter enables students to gather information related to a chemical equation. The chapter encompasses the limitations of a chemical equation.  It defines a catalyst and explains the nature and function of the same.

6. Chemical Reactions

The sixth chapter is also a lengthy one. It contains topics that need to be explained in a detailed manner. It comprises topics such as the four different types of chemical reactions, the reactivity series. It gives a detailed description and classification of oxides, whether acidic, basic, amphoteric, or neutral. The students hence will receive a vast amount of knowledge after studying this chapter.
