Oh, you are right. I should have asked like this: the electron of oxygen atom that is denoted by n=2, l=1 transferred to n=3, l=0 after the excitation process. At this moment, what is the electron's principal quantum number, two or three? But I think I got it after your message. It will be three.

Normally, Oxygen has 8 electrons in its neutral form that is 1s2 2s2 2p4. In this case, its principal quantum number (n) is two. But what happens if it got excited and its electronic configuration becomes 1s2 2s2 2p3 3s1? In this case, Is the principal quantum number (n) of oxygen two or...
