This video tutorial by Mr. Post explores the atom, the smallest particle of an element, and its components. It covers the structure of an atom, including the nucleus, protons, neutrons, and the electron cloud. The video explains subatomic particles, their characteristics, and relative mass. It also discusses the movement of electrons in orbitals, emphasizing the differences between protons, neutrons, and electrons in terms of mass and charge.
