Why do all bonds form?

• so the number of protons equals the number of electrons

• so an atom can become unstable

• to fill the outermost electron shell

Valence electrons are found

• in the innermost energy level of an atom

• in the middle energy levels of an atom

• in the outermost energy levels of an atom

Atoms are most stable when their outer shell is complete.

• true
• false
