Arrange the following atomic numbers in the increasing order of number

1.	Arrange the following atomic numbers in the increasing order of number of unpaired electronsA. 16B. 32C. 40D. 57
Answer» Electronic configuration is ` 1s^2 2s^2 2p^6 3s^2 3p^4` number of unpaired electrons is 2. Electronic configuration is Electronic configuration is ` 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^2`number of unpaired electrons is 2. Electronic configuration is ` 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^2` number of unpaired electrons is 2. Electronic configuration is `[Xe] 6s^2 5d^1` number of unpaired electrons 1 `therefore` order is (i) = (ii)= (iii) gt (iv)
