MCQ
The electron affinity of $Be$ is similar to :-
- ✓$He$
- B$B$
- C$Li$
- D$Na$
✓
Answer
Correct option: A.
$He$
a
He being noble gas has complete 1 st shell It has completed its duplet. While $B e$ Has electronic configuration $1 s^{2}, 2 s^{2}$ so be also has completely filled $2 s$ subshell so we can say that, The electron affinity of $B e$ is similar to $B e$ among the given options.
