Permittivity is a measure of how easy or difficult it is to form an electric field inside of a medium. Likewise, permeability is a measure of the ability to form a magnetic field inside of a medium. Permittivity Îµ and Îµ0. Permittivity is determined by how much a medium can polarize in response to an electric field. In cgs units, Îµ is unitless. In SI units, Îµ is in units of Farads/meter. This highlights the fundamental difference between the two measures of permittivity in the different unit systems.
Electronegativity. Electronegativity is a measure of the ability of an atom in a molecule to draw bonding electrons to itself. The most commonly used scale of electronegativity is that developed by Linus Pauling in which the value 4.0 is assigned to fluorine, the most electronegative element.lectrons to a reaction, while a high electronegativity implies that an element strongly seeks to. electrons in a reaction. The electron affinity is a measure of the energy change when an electron is added to a neutral atom to form a negative ion.
