The video tutorial covers atomic theory, starting with an overview of subatomic particles like protons, neutrons, and electrons. It explains the structure of the atom, including the nucleus and forces like the strong nuclear force. The tutorial introduces quarks and hadrons, discussing the Large Hadron Collider's role in particle physics. It also covers radioactivity, isotopes, and atomic mass, highlighting the differences between elements. Finally, Dalton's atomic theory is discussed, including its historical context and modern implications, such as the Bohr model of the atom.
