CHEMICAL BONDING NOTES All atoms want to attain a stable outer electron configuration (s2p6) and will form bonds with other atoms to attain this. The stronger the bon{ the greater the bond energ,y, and the shorter the bond distance between atoms DEFINITIONS r Chemical Bond: strong attractive force between atoms or ions in a compound . Ion an atom that has lost or gained electrons(s) . Valence electrons, electrons in the highest enefgy level (n -'1.-7) . Dipole a molecule where one part is partially positive and one part is partially negative, due to unequal sharing of electrons I Polyatomic lon _ a group of atoms that act as a single ion, ex. Nos I Molecule a group of atoms that is covalently bonded together BOND TYPES IONIC B9NDS transfer of electrons o One atom loses electron(s); one atom gains electron(s) . Form positive ions (cations) (+) and negative ions (anions)(-) o Held together by electrostatic attraction (opposites attract) r Strongest Bond tFpe; about 10o/o of all bonds are
