* Protons: These are positively charged particles that reside within the nucleus. The number of protons in an atom determines its atomic number and defines what element it is. For example, all carbon atoms have 6 protons.
* Neutrons: These are neutral particles, meaning they have no charge. They reside alongside the protons in the nucleus. The number of neutrons in an atom can vary, leading to different isotopes of the same element.
The nucleus is held together by a strong force called the strong nuclear force, which overcomes the electrostatic repulsion between the positively charged protons.
Here are some additional points:
* The nucleus is incredibly small, accounting for only a tiny fraction of the atom's overall volume.
* Almost all of the atom's mass is concentrated within the nucleus.
* The nucleus is the control center of the atom, containing the genetic material (DNA) in living organisms.
