Answer:

The Proton and the Neutron.

Explanation:

Electrons are part of the atom, but are "orbiting" around the nucleus, which is composed of the protons and neutrons. The protons determine the elemental properties (valence states) and the neutrons determine the isotope and total mass (with the protons).
