PHYSICS - Matter - Atom Structure

This video tutorial covers the basics of atomic structure, including the concepts of atomic number and mass number. It explains how atoms can become ions by gaining or losing electrons, affecting their charge. The video also introduces isotopes, which are forms of elements with the same number of protons but different numbers of neutrons, leading to different mass numbers. The tutorial uses the periodic table to illustrate these concepts and emphasizes the importance of understanding these ideas in both chemistry and physics.

What determines the identity of an element in terms of atomic structure?

Explain the difference between atomic number and mass number.

How can you calculate the number of neutrons in an atom?

What happens to an atom when it becomes an ion?

Describe what isotopes are and how they differ from one another.
