Chewy goodness...
Oh, no, sorry, that's the center of a tootsie pop.
I'll go with "Nucleus" for an atom. Protons and neutrons. Then possibly smaller particles that make up the protons and neutrons, called quarks. Then possibly tiny bands of energy called "strings." But string theory is still, well... theoretical.

atoms were found to be divisible and composed of smaller subatomic particles.
Most atoms are composed of three types of subatomic particles which govern their external properties:
electrons, which have a negative charge and are the least massive of the three;
protons, which have a positive charge and are about 1836 times more massive than electrons; and
neutrons, which have no charge and are about 1839 times more massive than electrons.
Protons and neutrons make up a dense, massive atomic nucleus, and are collectively called nucleons. The electrons form the much larger electron cloud surrounding the nucleus.
Atoms can differ in the number of each of the subatomic particles they contain. Atoms of the same element have the same number of protons (called the atomic number). Within a single element, the number of neutrons may vary, determining the isotope of that element. The number of electrons associated with an atom is most easily changed, due to the lower energy of binding of electrons. The number of protons (and neutrons) in the atomic nucleus may also change, via nuclear fusion, nuclear fission or radioactive decay, in which case the atom is no longer the same element it was.
Atoms are electrically neutral if they have an equal number of protons and electrons. Atoms which have either a deficit or a surplus of electrons are called ions. Electrons that are furthest from the nucleus may be transferred to other nearby atoms or shared between atoms. By this mechanism atoms are able to bond into molecules and other types of chemical compounds like ionic and covalent network crystals.
Atoms are the fundamental building blocks of chemistry, and are conserved in chemical reactions.

There are three types of sub-atomic particles:
PROTONS (+ve charge)
NEUTRONS (no charge)
And these occur in the nucleus:
ELECTRONS (-ve charge)
These circulate around the nucleus.
The number of protons = the number of electrons
In this highly simplified diagram of a carbon atom, 6 protons and 6 neutrons make up the nucleus and 6 electrons circulate in two orbits around the nucleus.

The center of an atom is the nucleus, which contains positively charged protons & uncharged neutrons. Negatively charged electrons "orbit" the nucleus. You could break these down into even smaller particles, but I won't get into that here.

The nucleus??? I guess that's right I see 2 other people said the same thing. I guess I did pay attention in Science.

A nucleus, composed of protons and neutrons (among other theoretical particles).

Nucleus, it has protons and neutrons.
