1. The number of protons in an atom equals the elemental identity, or the atomic number.

2. Electrons are negatively charged particles circling the nucleus in the electron cloud surrounding the atom.

3. Matter comprised of only one type of atom is an element.

4. The building block of matter is the atom.

5. Neutral particles within the nucleus are neutrons. They serve to bind the atom together by negating the repulsive force of the protons.

6. The center of the atom is the nucleus.

7. The positively charged particle is the proton.
