Valence Electrons
Electrons in the outer shell of an atom that determine the atom's chemical properties and its ability to form bonds with other atoms.
Atomic Number
The number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table.
Atomic Mass
The mass of an atom, typically expressed in atomic mass units (amu), representing the total number of protons and neutrons in the nucleus.
