All matter is made of atoms

Most mass in an atom is in the nucleus

Positively charged atoms with electrons. "Plum pudding"

electrons travel in fixed orbits

All atoms go with their appropiate element

Electrons could go between the orbits while releasing specific amounts of energy

Small dense nucleus in atom that is surrounded by electrons

"Atomos" atoms always move

In chemical reactions, atoms are separated, combined, or rearranged.

electrons travel in paths/energy levels
