Read each question carefully and answer to the best of your ability. Use your knowledge of atomic structure and chemical bonding to explain the processes involved in ion formation.
1. What is the primary reason atoms form ions?
To increase their atomic mass
To achieve a stable electron configuration
To become more reactive
To change their number of protons
2. An atom that *loses* electrons becomes a(n):
Anion
Cation
Isotope
Molecule
3. Atoms achieve a stable electron configuration by having a full outer shell, typically with valence electrons.
4. A positively charged ion is called a(n) , formed when an atom electrons.
5. A negatively charged ion is called a(n) , formed when an atom electrons.
6. Nonmetals tend to gain electrons to form negative ions.
True
False
7. The number of protons in an atom changes when it forms an ion.
True
False
8. Explain how a neutral sodium atom (Na) forms an ion. Include the number of electrons gained or lost and the resulting charge.
9. Describe the difference between a cation and an anion, providing an example of each.
10. Observe the image below. If this atom were to form an ion, would it gain or lose electrons? Explain your reasoning.
