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 energy level
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
An atom with 3 valence electrons "wants" a full shell, so it can either gain 5 or lose 3. Which is more likely to occur?
