Question

Write the correct order of filling up of electrons in subshells, 4p, 4d, 5s,

5p​

Answer 1

Answer:

4p,5s,4d,5p is the correct order

Explanation:

1s,2s,2p,3s,3p,4s,3d,4p,5s,4d,5p,6s,4f,5d,6p,7s,5f,6d,7p

Answer 2

Answer:

n+l values of the given orbitals are 5, 5, 6, 6 respectively. Among first two 4p has lower
