Question

What is the order of successive ionisation enthalpies? (A) IEIII > IEII > IEI (B) IEI > IEII > IEIII (C) IEII > IEI > IEIII (D) IEIII > IEI > IEII

The ionization energy of a multivalent atom increases with a consecutive removal of an electron. This is due to an increase in effective nuclear charge on the valence electron that makes it difficult to ionize a cation.
Therefore

I E_{1} < I E_{2} < I E_{3}

Q. What is the order of successive ionisation enthalpies?

$I E_{III} > I E_{II} > I E_{I}$

$I E_{I} > I E_{II} > I E_{III}$

$I E_{II} > I E_{I} > I E_{III}$

$I E_{III} > I E_{I} > I E_{II}$

The ionization energy of a multivalent atom increases with a consecutive removal of an electron. This is due to an increase in effective nuclear charge on the valence electron that makes it difficult to ionize a cation.
Therefore $I E_{1} < I E_{2} < I E_{3}$

IEIII​>IEII​>IEI​

IEI​>IEII​>IEIII​

IEII​>IEI​>IEIII​

IEIII​>IEI​>IEII​

The ionization energy of a multivalent atom increases with a consecutive removal of an electron. This is due to an increase in effective nuclear charge on the valence electron that makes it difficult to ionize a cation. Therefore IE1​<IE2​<IE3​

$I E_{III} > I E_{II} > I E_{I}$

$I E_{I} > I E_{II} > I E_{III}$

$I E_{II} > I E_{I} > I E_{III}$

$I E_{III} > I E_{I} > I E_{II}$

The ionization energy of a multivalent atom increases with a consecutive removal of an electron. This is due to an increase in effective nuclear charge on the valence electron that makes it difficult to ionize a cation.
Therefore $I E_{1} < I E_{2} < I E_{3}$
