Question

Electron configuration for excited state of atomic oxygen

Answer 1

Answer:...........................mmmmmmmmmmm

Explanation:

Answer 2

If the element were to become excited, the electron could occupy an infinite number of orbitals. However, in most texts the example will be the next available one. So for oxygen, it might look like this: 1s22s22p33s1 - where the valence electron now occupies the 3s orbital in an excited (i.e. not ground) state.
