Question

Difference between ionisation energy, electronegativity and electron affinity

Answer 1

Answer:

ionisation energy - the energy required to remove last e from 1 mol of any substance only in gaseous state !

electronegativity - the ability of atom to attract the shared pair of e towards it

electron affinity - the ability to keep the electron with it

the sign of electronegativity is reversed to get electron affinity ..

( more or less , the terms r interchanged by some )

for all above cases related Q u should remember , the 2 conditions :-

◆ gaseous state only

◆ 1 mole of the given substance

good day

Answer 2

Answer:

:Electron gain enthalpy

Tendency to gain electrons for an isolated gaseous atom is its electron gain enthalpy.

Electronegativity

Tendency to attract the shared pairs of electrons for an atom which is in chemical compound is its electronegativity.
