Most of the volume of the atom is occupied by the electrons ● Atomic Numbers and Mass Numbers ○ Element: a substance whose atoms all contain the same number of protons ○ Atomic Number: assign each element a unique number, equal to the same number of protons ○ Mass Number: sum of the protons and neutrons within the nucleus of an atom

Explanation:

The bulk of the volume of any given atom is occupied by its electrons.

Atoms consist of protons, neutrons, and electrons. Protons and neutrons are located in the nucleus of the atom while electrons are in the shells outside the nucleus.

The nucleus takes a larger portion of the mass of atoms because protons and neutrons cumulatively  form a heavier weight than electrons.

However, the nucleus represents a small percentage of the volume of the atom. The diameter of the nucleus of an atom is about 100,000 times smaller than the entire diameter of an atom.

Thus, if the volume of the nucleus is a very small portion of the volume of an atom, it means that the electrons occupy a much larger portion - the remaining portion of the atom.
