13.1 Types of Chemical Bonds Spectroscopy = the study of the interactions of EM-Rad with matter Energy of interaction between a pair of ions can be calculated by using Coulomb’s Law o V = 2.31 x 10 -19 J nm (Q 1 Q 2 )/r V = joules r = distance between the ion centers (nm) Q 1 and Q 2 = numerical ion charges o Negative sign indicates an attractive force

Unformatted text preview: The ion pair has lower energy than the separated ions o Can also be used to calculate the repulsive energy when two like-charged ions are brought together (calculated energy will have a positive sign) Bonding occurs if the energy of the aggregate is lower than that of the separated atoms...
