Please answer this question:
After np orbitals are filled, the next orbital filled will be:
(A) (n + 1) s
(B) (n + 2) p
(C) (n + 1) d
(D) (n + 2) s
Dear student,
After the filling of np-orbitals, the (n+1)s orbitals are filled next. As per Aufbau principle, orbitals are filled in order of increasing value of (n+l). If two orbitals possess same (n+l) value, then orbital having lower value of n is filled first.
Further you can refer to the following image for the trend
