Read each question carefully and answer to the best of your ability. Show all your work where applicable. This worksheet will test your understanding of ionic charges and how they relate to atomic structure.
1. What is an ion?
An atom with a neutral charge
An atom that has gained or lost electrons
A molecule formed by two atoms
A subatomic particle
2. What charge does an atom have if it loses electrons?
Negative
Positive
Neutral
No charge
3. An atom that gains electrons becomes a ion.
4. The force that holds ions together in a compound is called an bond.
5. All atoms naturally have a neutral charge.
True
False
6. Cations are ions with a negative charge.
True
False
7. Explain the difference between a cation and an anion.
8. Why do atoms form ions?
9. Observe the diagram of an atomic structure below. If this atom were to lose one electron, what would its ionic charge be? Explain your reasoning.
