Nothing. An atom is primarily empty space. If the nucleus of a hydrogen atom was a football, the atom itself would be the size of a football stadium, with nothing else inside but the football. There are three things that make up the volume of atoms. The three things that make up the volume of atoms are protons, electrons and neutrons.
An atom that has the same amount of electrons and protons fills up the majority of an atom.
In the classic model, from the simplified Bohrs model, the answer is simply: nothing. It is mostly void of anything at all.
Empty space.
Most of the mass is in the nucleus; most of the volume is in the electron "cloud".

Atoms.
Protons believe me

Carbon and hydrogen atoms.
Empty space makes up most of the volume of an atom. The nucleus (protons and neutrons) make up most of the mass.

Plasma makes up 55% of blood volume.
The nucleus makes up most of the mass and the other things in the atom make up the rest.
Water.

Nitrogen makes up roughly 80% of Earth's atmosphere (Oxygen makes up most of the remainder).
