Question

Difference between ionization energy, electron gain enthalpy and electronegativity

Answer 1

ionization energy is the amount of energy is required for the removal of outer valence electron of that atom in gaseous state :)

M + energy -----> M+ e-
if its first electron its called 1s tionization energy if second electron its called 2 nd ionization energy

where as electron gain enthalapy or electron affinity is the amount of energy released when one extra electron is added to the atom
M+e- ----> M + energy

Answer 2

electronegativity is the the tendency of an atom or a functional group to attract electrons (or electron density) towards itself.

Answer 3

Thankyou @chmvijay :)

Answer 4

ur welcome

Answer 5

ionization energy is the minimun energy required when an electron is removed from the valance shell of an isolated atom to form an ion.[cation]
electron affinity is the energy released when an electron is gained by an atom to form an anion
electronegativity is the power to attract shared pair of electrons b/w two atoms in a bond

Answer 6

Cl +e------Cl[negative] E.A=399Kg/mol
