WHO MADE THESE ATOMIC DISCOVERIES?

An atom has a nucleus that is very small
In a reaction, the mass of the products must equal the mass of the reactants.

Electrons are negatively charge pieces of matter.

An electron has a mass that is very small compared to the size of the atom.

The charge to mass ratio of an electron

Any sample of a chemical compound will contain the same elements in the same
proportions.

Neutrons are a particle with no charge.

The magnitude of an electron's charge
