Read each question carefully and answer to the best of your ability. This worksheet will help you understand the basics of ions.
An atom is the basic unit of matter. It is made up of even smaller particles called protons, neutrons, and electrons. Protons have a positive charge, electrons have a negative charge, and neutrons have no charge.

1. Which subatomic particle has a positive charge?
Electron
Neutron
Proton
Nucleus
2. What happens to an atom if it gains electrons?
It becomes positively charged.
It becomes negatively charged.
Its charge stays the same.
It becomes neutral.
3. An atom that has gained or lost electrons is called an .
4. If an atom loses electrons, it becomes a ion.
5. The particles in an atom that have no charge are called .
6. All atoms naturally have a neutral charge.
True
False
7. A positive ion has more electrons than protons.
True
False
8. Explain in your own words what an ion is.
9. Describe the difference between a positive ion (cation) and a negative ion (anion).
