MCQ
In the sixth period, the orbitals being filled are :-
- A$5s, 5p, 5d$
- B$6s, 6p, 6s, 6f$
- C$6s, 5f, 6d, 6p$
- ✓$6s, 4f, 5d, 6p$
✓
Answer
Correct option: D.
$6s, 4f, 5d, 6p$
d
In the sixth period $( n =6)$ of the periodic table, $6 s , 4 f , 6 d , 6 p$ orbitals are filled in the increasing order of the energy. A total of $16$ orbitals are available each of which contains a maximum of $2$ electrons. Thus, a total of $32$ electrons can be accommodated.
