Chemical Bond:
A chemical bond is a force of attraction between
atoms or ions. Bonds form when atoms share or transfer valence electrons.
Valence electrons are the electrons in the outer energy level of an atom that
may be involved in chemical interactions. Valence electrons are the basis of
all chemical bonds.
