Introduction to Atoms and Subatomic Particles

The video tutorial explains the concept of atoms, their sub-atomic particles, and how they form elements. It covers the roles of protons, neutrons, and electrons, and how they contribute to the stability and charge of an atom. The tutorial also discusses electron orbits, their capacities, and the concept of electron clouds. Finally, it introduces the periodic table and the arrangement of elements.

What are the three sub-atomic particles that make up an atom?

• Protons, Neutrons, Electrons
