- 1. Multiple Choice
Why do all bonds form?
to fill the outermost energy level
so an atom can be unstable
so the number of protons and electrons can equal.
so they can gain neutrons.
- 2. Multiple Choice
Valence electrons are found
outermost energy level
innermost energy level
some where in the electron cloud
- 3. Multiple Choice
