A) \[B>Be\]
B) \[Be>B\]
C) \[Be=B\]
D) None of these
Correct Answer: B
Solution :
lonization potential of Be is greater than B because in\[Be(1{{s}^{2}},2{{s}^{2}})\]s-subshell is completely filled and therefore, more energy is required to remove electron from outermost shell than\[B(1{{s}^{2}},2{{s}^{2}},2{{p}^{1}})\]
