NationMaster - Encyclopedia: Mulliken scale

The Mulliken scale (also called Mulliken-Jaffe scale) is a scale for the electronegativity of chemical elements. It was developed by Robert S. Mulliken in 1934. It is based on the Mulliken electronegativity, c_M, which is related to the electron affinity EA_v (the tendency of an atom to become negatively charged) and the ionization potential IE_v (the tendency of an atom to become positively charged):

c_M = (IE_v + EA_v)/2

Some example values:

Element	Al	Ar	As	B	Be	Br	C	Ca	Cl	F	Ga	Ge	H	I	In	K	Kr	Li
c_M	1.37	3.36	2.26	1.83	1.99	3.24	2.67	1.30	3.54	4.42	1.34	1.95	3.06	2.88	1.30	1.03	2.98	1.28

Element	Mg	N	Na	Ne	O	P	Rb	S	Sb	Se	Si	Sn	Sr	Te	Xe
c_M	1.63	3.08	1.21	4.60	3.21	2.39	0.99	2.65	2.06	2.51	2.03	1.83	1.21	2.34	2.59

	Two scales of electronegativity are in common use: the Pauling scale (proposed in 1932) and the Mulliken scale (proposed in 1934).
	On this scale, the most electronegative element (fluorine) is given an electronegativity value of 4.0; the least electronegative element (francium) has a value of 0.7, and the remaining elements have values in between.
	On the Mulliken scale, numbers are obtained by averaging ionization potential and electron affinity.

	The Richter scale, the Mercalli scale, the Rossi-Forel scale and the Omori are all used to measure the intensity of earthquakes.
	The Fujita scale measures the intensity of tornadoes.
	The Torino scale and the Palermo scale measure the impact hazard level of near-Earth objects such as asteroids.
