Glossary
Electrical resistivity | Electronegativity | Electronic configuration

Electrical resistivity
Electric field strength divided by current density when there is no electromotive force in the conductor. Resistivity is an intrinsic property of a material. For a conductor of uniform cross section with area (A) and length (l), and whose resistance is (R), the resistivity is given by

ro =  R × A 
 l 

Electronegativity
Electronegativity is a parameter originally introduced by Pauling which describes, on a relative basis, the power of an atom or group of atoms to attract electrons from the same molecular entity.

Electronic configuration
Electronic configuration is the arrangement of electrons in an atom when it is in its ground state. All the properties of elements depend on their electronic configuration.
