Q. $A \rightarrow A^{+} + e,\ E_{1}\ and\ A^{+} \rightarrow A^{2 +} + e,\ E_{2}.$ The energy required to pull out the two electrons are $E_{1}\ and\ E_{2}$ respectively. The correct relationship between two energy would be
A) $E_{1} < E_{2}$
B) $E_{1} > E_{2}$
C) $E_{1} = E_{2}$
D) $E_{1} \neq E_{2}$
Explanation
(a)
$E_{1} < E_{2}$, because second IE is greater than first IE
