Atomic Structure and Subatomic Particles

This video tutorial explains the basic structure of atoms, which are the fundamental units of matter. It covers the components of an atom, including the nucleus made up of protons and neutrons, and the surrounding electrons. The video details the electrical charges of these subatomic particles and introduces the concept of electron shells and the electron cloud model. It concludes with a summary of how these components contribute to the overall mass and electrical neutrality of an atom.
