Answer:
C
Explanation:
An atom consists of protons (positively charged particles), electrons (negatively charged particles), and neutrons (neutral particles that carry no charge).
For an atom to be neutral, there needs to be an equal amount of protons and electrons, or there is one too few electrons then the atom is positively charged, and negatively charged if there are one too many electrons.
The model of the atom shows that there is a center mass, with electrons spinning around it. The center mass is known as the nucleus and consists of protons and neutrons. The particles that move around the nucleus are called electrons.
