No electrons do not orbit the nucleus like planets

is a series of models that developed from experimental evidence

electrons move only in specific orbits around an atom's nucleus, each has specific energy

Chadwick showed that another particle exists in the nucleus of atoms. This particle is called a neutron.

Rutherford concluded that the atom is mostly empty space /has a dense, positive charge at its center. This dense center is called the nucleus. (The plural of n

Atom is the smallest unbreakable unit of matter /An atom of one element cannot be changed into an atom of a different element by a chemical reaction./

Atoms contain negatively charged particle called electron /Atoms have no electrical charge
