The nucleus of an atom contains chromosomes

Atoms are big enough to see with the human eye.

Electrons are arranged in shells around the nucleus.

Electrons have a larger mass than protons or neutrons.

Electrons have a relative charge of +1 and a relative mass that is usually ignored (it is ‘negligible’).

Neutrons are electrically neutral.

Protons have a relative charge of +1 and a relative mass of 1

Dalton's model of the atom included the sub-atomic particles.
