Question: What are atoms made of?
Answer: Atoms are the smallest part of an element (single substances, such as copper, gold, and carbon).
Atoms can be divided into two basic regions:
1. The region in the center of an atom is called the nucleus. Particles inside the nucleus are called nucleons, such as protons and neutrons.
- Protons are positively charged particles.
- Neutrons are particles without a charge.
2. The region outside the nucleus is where the atom’s electrons move.
While there are no real boundaries that hold nucleons inside the nucleus or to contain electrons within a certain distance from the nucleus, the atomic particles remain in certain areas.
Electrons farthermost from the nucleus are more easily rubbed off—pulled away by another atom–or shared with another atom.
