i. Observed outer electronic configuration of europium (Eu) is 6s2 4f7 5d0.
ii. In the observed electronic configuration of Eu, 4f subshell is half-filled which is a highly stable configuration. Therefore, observed electronic configuration...
i. 2He: 1s2
Here, n = 1. Therefore, 2He belongs to the 1st period.
The shell n = 1 has only one subshell, namely 1s. The outer electronic configuration 1s2 of ‘He’ corresponds to the...
