Why are electrons and their behavior the central focus of general chemistry?

• A. Because electrons are the heaviest subatomic particles and contribute most to atomic mass.
• B. Because electrons determine how atoms interact and bond with each other, influencing chemical reactions and properties.
• C. Because electrons are responsible for the color of all chemical compounds.
• D. Because electrons are located in the nucleus and control nuclear stability.

Answer: (B)

Verified step by step guidance

1. Understand that in general chemistry, the focus is on how atoms interact and form compounds, which is governed by the behavior of electrons.
2. Recall that electrons are negatively charged particles located in regions around the nucleus called orbitals, and their arrangement determines how atoms bond.
3. Recognize that electrons participate in chemical bonds by being shared, transferred, or pooled between atoms, which directly affects chemical reactions and properties.
4. Note that electrons are much lighter than protons and neutrons, so they do not contribute significantly to atomic mass, nor are they located in the nucleus.
5. Conclude that the central role of electrons in determining chemical behavior makes them the primary focus in general chemistry.
