The Structure and Composition of Atoms

The video tutorial explains the structure of an atom, focusing on the nucleus, which contains most of the atom's mass but occupies minimal space. It describes the roles of protons and neutrons within the nucleus, including their charges and masses measured in atomic mass units (AMU). The tutorial further explores how the number of protons, known as the atomic number, differentiates elements, using examples like helium, aluminum, hydrogen, and oxygen.
