The nucleus itself is generally made of protons and neutrons but even these are composite objects. Inside the protons and neutrons, we find the quarks, but these appear to be indivisible, just like the electrons.
core of protons and neutrons surrounded by electrons
Explanation:
An atom consists of three sub atomic particles which are protons, neutrons, and electrons.
Protons have a positive charge, neutrons have no charge, and electrons have a negative charge.
Both protons and neutrons are placed inside the nucleus of an atom. This nucleus is surrounded by the electrons as electrons revolve around the nucleus.
Thus, we can conclude that out of the given options, a core of protons and neutrons surrounded by electrons best describes an atom.
