Charges in Atoms, Atomic Models, and Quantum Numbers

The video tutorial explains the basic structure of an atom, including protons, neutrons, and electrons. It covers how to determine the number of neutrons using atomic mass and number, and describes the formation of ions. The Bohr model is introduced as a historical representation of atomic structure, followed by the Quantum Mechanical Model, which provides a more accurate depiction of electron behavior using probability clouds.

What happens to an atom when it gains or loses an electron?

Describe the Bohr model of the atom.

What is the Heisenberg uncertainty principle and its significance in atomic theory?
