		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.

	Electronegativity
		The Pauling Scale is a widely used, empirical scale of electronegativity values, originally developed by Linus Pauling in 1932.
		On this scale, the most electronegative element (fluorine) is given a value of 4.0, while the least electronegative element (francium) is given a value of 0.7.
		Bonds between atoms with a large electronegativity difference (greater than or equal to 2.0 on the Pauling scale) are usually considered to be ionic, while values between 2.0 and 0.4 are considered polar covalent.

		Originally and correctly, G ''scale'' is the use of 45mm gauge track, as used in standard gauge I scale (NEM 010), aka 3/8" scale (NMRA S-1), for modelling metre gauge narrow gauge railways, using the correct scale of 1:22.5.
		N scale uses 9 mm gauge track, and a scale of 1:160 worldwide, except for the United Kingdom where a scale of is 1:148 is used because of the problems early on in fitting mechanisms into smaller British trains.
		Unlike other scales and gauges, which were de facto standards at best, within two years N scale defined the gauge, voltage, and polarity of track, as well as the height and type of couplers.

		The interpretation is that bonds between atoms of the same kind involve equal sharing of electrons, while those between atoms of different kinds involve unequal sharing, and thus adding a coulombic contribution to the bond strength.
		Mulliken used ionization energy and electron affinity, plus a scaling factor, to come up with essentially the same numbers.

	n scale
		N scale is a popular model railway standard, allowing hobbyists to either build layouts that take up less space than HO scale, or to pack longer runs with more detail into a similar amount of space.
		N scale uses 9 mm-gauge track, and a scale of 1:160 worldwide, except for the United Kingdom where a scale of is 1:144 is used because of the problems early on in fitting mechanisms into smaller British trains.
		2mm scale, as the name implies, is scaled at 2mm to the foot (1.152) with a 9.42mm track gauge.

		Secondly, it is somewhat surprising to see the authors supporting Allen's scale of electronegativity and his claimed "third dimension" to the periodic table, which, as several authors have argued, has very little to commend it (3, 4).
		This statement too is incorrect, since the Mulliken scale, which takes the average of ionization energy and electron affinity, also shares this virtue.
		The unstated rationale for favoring Allen's scale of electronegativity seems to be that it maintains the connection with ionization energy that is used by the authors to develop shell structure, but this is hardly a compelling reason for choosing Allen's particular function of ionization energies.

	o scale
		O scale (or O gauge) is a scale commonly used in model railroading.
		While 1:48 is a very convenient scale for modeling using the Imperial system (a quarter-inch equals one scale foot), the discrepancy between O scale in the United States and in Europe is attributed to Lionel misreading the original Märklin specifications.
		While normally the use of scale or gauge is equivalent, O gauge tends to more often mean semi-scale three-rail toy trains, while O scale carries the connotation of two-rail equipment, because of its greater "scale" accuracy, though standard two-rail trains still have an inaccurate gauge, track and wheel profiles.

		Values below 0.4 are considered non-polar covalent bonds, and electronegativity differences of 0 indicate a completely non-polar covalent bond.

	Re: How did Pauling come up with 4 as the electronegativity for F ? Is it 3.98?
		He ASSIGNED Fluorine a value of 4.0 and was able to scale all the other elements by measuring and deriving electronegativity differences.
		The discrepency between Pauling's 4.0 and other scales' use of 3.98 is probably due to the fact that Pauling calculated electronegativety values from a rather complicted wave funtion analysis which I won't go into here (I'm not even sure I completly understand it myself !).
		The other scales tend to use simple functions based of ionization potential and/or electron affinity and there is probably some sources of error with the values in IP and EA.

	Ionization Energy
		There are three main scales use to calculate the electronegativity, the Pauling, Mulliken, and Allred-Rochow scales.
		The Mulliken scale calculates electronegativity as the average of the ionization energy and the electron affinity.
		This scale is beneficial because it takes into account the differences in electronegativites of different orbitals as well as the atom's state of hybridization.

		A third scale of electronegativities which is now much in favour is the Allred-Rochow scale, about which you will hear later.
		The result of all these scales is that electronegativities are high for small atoms and/or atoms with high values of Z
