IE,IP) ionisation potential. Compare with adiabatic ionisation energy, vertical ionisation energy, electronegativity, and electron affinity. The energy needed to remove an electron from a gaseous atom or ion. 

Ionization energy, electronegativity, and electron affinity generally increase as you move across a period and decrease as you move down a group.

As our previous discussions of ionization energy, electronegativity, and electron affinity would suggest, ionic bonding can occur easily when elements that have low... 

Now, we would like to derive the change in total energy, electronegativity and chemical hardness values among the reactants of (HSAB1)-(HSAB4) reactions and of their inter-correlations, employing different theoretical and computational methods. 

First, the relativistic stabilization of the 7s orbital. Due to this large relativistic effect the first ionisation energy, electronegativities, and polarizabilities of superheavy elements like 111 or 112 are expected to be relativistically increased (see for example the discussion in Ref. 96). The 7s orbital is stabilized to a much greater extent than the 7pi/2 orbital.
