Question

What is the order in which the three subshells fill in a 3d orbital?
1) 3p, 4s, 5d
2) 4p, 5s, 6d
3) 4p, 5s, 4d
4) 5p, 6s, 5d

Answer 1

Answer:

3) 4p, 5s, 4d

Step-by-step explanation:

The order in which the subshells fill in a 3d orbital follows the rules of the Aufbau principle and the order of increasing energy levels.

The correct order in which the subshells fill in a 3d orbital is:

4p, 5s, 4d
