Question
35. What is the correct way of writing electronic configuration? E.g. for Zn (which is correct between the two) 1)1s2 2s2 2p6 3s2 3p6 3d10 4s2 2) 1s2 2s2. 2p6. 3s2. 3p6. 4s2. 3d10 & Therefore, how would we find kernel electrons?Will we exclude 4s2 subshell or 3d10 subshell while writing kernels?
