The video explains that atoms are composed of protons, neutrons, and electrons, with the identity of an atom determined by its protons. Atomic models are developed through experiments, and electrons exhibit both particle and wave behaviors. Electrons' positions are probabilistic, leading to the concept of orbitals. These orbitals influence chemical interactions, which are fundamental to the nature of matter.
