MCQ
When $3d$ orbital is complete, the new electron will enter the
- ✓$4p$-orbital
- B$4f$-orbital
- C$4s$-orbital
- D$4d$-orbital
✓
Answer
Correct option: A.
$4p$-orbital
a
(a) According to the Aufbau’s principle the new electron will enter in those orbital which have least energy. So here $4p$- orbital has least energy then the others.
