What you need to learn in this chapter
In this chapter, we will be learning about matter and its different forms. We will explore atoms, molecules, and ions, and understand how they make up everything around us.
We will also study the existence of elements in various forms and how they are classified in the Modern Periodic Table of Elements. We will analyze the table and deduce the principles behind arranging the elements.
Additionally, we will learn about isotopes, which are atoms with the same number of protons but different numbers of neutrons. We will study examples of isotopes and learn how to determine the number of protons, neutrons, and the nucleon number of isotopes.
