Subatomic Particles and Atomic Structure

The video tutorial reviews the structure of an atom, focusing on the subatomic particles: protons, neutrons, and electrons. It explains their masses, charges, and locations within the atom. The nucleus contains protons and neutrons, while electrons are in the electron cloud. The tutorial uses a lithium atom model to illustrate these concepts, showing how electrons occupy energy levels. The first energy level holds up to two electrons, and the second can hold up to eight. The video aims to help students understand atomic structure as per the TEK 8.5A standard.
