MCQ
Isoelectronic species are
- ✓${K^ + },\,C{l^ - }$
- B$N{a^ + },\,C{l^ - }$
- C$Na,\,Ar$
- D$N{a^ + },\,Ar$
✓
Answer
Correct option: A.
${K^ + },\,C{l^ - }$
a
(a) ${K^ + } = \,1{s^2}\,2{s^2}2{p^6}3{s^2}3{p^6}$
(a) ${K^ + } = \,1{s^2}\,2{s^2}2{p^6}3{s^2}3{p^6}$
$C{l^ - } = \,1{s^2}2{s^2}2{p^6}3{s^2}3{p^6}.$
