Answer:
The answer is electrons.
Explanation:
An atom is the smallest unit or building block of any matter. The atoms can further be divided into three subparts that are neutrons, protons, and electrons.
Each of these sub-units has an associated charge on them. The protons contain a positive charge, electrons contain a negative charge and neutrons do not have any charge on them.
The neutrons and protons are present inside the nucleus of the atom and the electrons revolve in orbits around them.
As electrons are what takes up space in the atom, the result is that the size of the biggest filled orbital determines the size of the atom.
Hence the electrons determine the size of an atom.
