Structure of an Atom: Thomson's Model of an Atom

The video explores the nature of charged particles and the evolution of atomic models. It begins with Dalton's model, which considered atoms indivisible. Goldstein's discovery of canal rays and Thomson's identification of electrons challenged this view, leading to the concept of subatomic particles. Thomson's model likened the atom to a pudding cake, with electrons embedded in a positive sphere. Rutherford's gold foil experiment further refined the atomic model, introducing the nucleus containing protons and neutrons, with electrons orbiting outside.

What does it mean for an atom to be neutral?

Describe the differences between protons, electrons, and neutrons.
