Problem 7P
What is the key distinction between sublevel energies in one- electron species, such as the H atom, and those in many-electron species, such as the C atom? What factors lead to this distinction? Would you expect the pattern of sublevel energies in Be3+ to be more like that in H or that in C? Explain.

ANSWER:
Solution 7P:
Step 1:
Here, we are going to explain the difference between the sublevel energies in one- electron species and many-electron species.
In one- electron species, all the sublevels have same energy.
On the other hand, in many-electron species, the energy level splits into sublevels having different in energy.
For example:
One -electron species ( H atom) , principal quantum number, n =1
Angular quantum number, l =0, the orbital is 1s
But for C-atom, principal quantum number, n =4
Angular quantum number, l =0, 1, 2, 3
The subshell are 1s, 2s, 2p and 3s with different energy.
