The center of an atom is called its nucleus.

There are three types of subatomic particles: protons, neutrons, and electrons.

The nucleus contains all the protons and neutrons in the atom, which also weigh the most out of the three tyes of subatomic particles.

Surrounding the nucleus are the atom's electrons, which orbit the atom similar to how the planets in our solar system orbit the Sun.

Answer:

Nucleus, protons and neutrons

Explanation:

An atom has a nucleus and and orbitals, the nucleus holds protons and neutrons while the orbitals hold electrons.

There are 3 types of particles, protons +, neutrons, o, and electrons -.

We could think of atoms like the Solar System. The sun is in the center and the orbits are where the planets go around.

An atom has a nucleus for the sun and orbitals as the orbits, electrons are the planets.

The nucleus hold protons and neutrons.

Which means the center of an atom is the nucleus and the nucleus holds protons and neutrons.
