Valence electron cloud in ionic bonding the valence electrons are completely transferred from one atom to the other atom. Reading the different types of bonds atoms form bonds with other atoms in order to have a full outer shell of electrons like the noble gases. The answer has to do with electronegativity, which is the ability of atoms to attract electrons to themselves. If an atom has too few or too many valence electrons it will have to gain, lose, or share those outer electrons with another atom in order to become happy or in chemistry terms, more stable.
