What term refers to the center of an atom where protons and neutrons are located?

Explanation:
The center of an atom houses the nucleus, where protons and neutrons are located. The nucleus contains almost all of the atom’s mass and is made of positively charged protons and neutral neutrons, collectively called nucleons. Electrons reside outside the nucleus in the electron cloud or electron shells. Terms like proton cloud describe a region associated with protons and aren’t accurate for the center, while nucleoid refers to a region in some bacteria containing DNA, not atomic structure. So the center is the nucleus.
