Chapter 2: Matter and Atomic Structure
What you need to learn in this chapter
In this chapter, we will be learning about matter and atomic structure. We will start by understanding the basic concepts of matter, such as how to describe it and explain changes in its state.
Next, we will explore the development of the atomic model, including the subatomic particles found in atoms and their relative mass and charge. We will also study the structure of the atom, including the proton number, nucleon number, and the number of electrons in an atom.
Lastly, we will learn about isotopes and their uses, including how to deduce their meaning and calculate the relative atomic mass of isotopes.
