Which of these have no unit?
Options
(a) Electronegativity
(b) Electron affinity
(c) Ionisation energy
(d) All of these
Correct Answer:
Electronegativity
Explanation:
Electronegativity is unit less quality. Pauling scaleand Mulliken scale are used to determine electronegativity Electron affinityy and ionisation energy are expressed in kJ/mol and eV/atom respectively.
