Question

8. What is the value of electron gain enthalpy of Nat if
IE, of Na = 5.1 eV? [AIPMT (Mains)-2011]
(1) +2.55 eV
(2) +10.2 eV
(3) -5.1 eV
(4) -10.2 eV​

Answer 1

Answer:

2

Explanation:

Answer 2

Hey mate,

As we know That I.E is the minimum amount of energy required to remove

an electron from the valence shell of an isolated gaseous atom in it 's Ground

state resulting in the formation of ion whereas , Electron gain enthalopy is the Amount of energy associated with the

gain of electrons by the isolated Gasiot Atom.

So, It is Opp of I.e .

Hence, If I.e of Na = 5.1 .

It's electron gain enthalopy will be :

5.1 .

Hope it is helpful...
