Question

Classify the following atom as excited, ground state, or not possible.

1s^2 2s^2 2p^6 3p^1

I'm unsure of how to find the answers from the electron config.

Answer 1

HI, umm.. from the config, the 3s orbital was kinda skipped.. so i assume the atom may be excited. the usual config would have the 3s orbital coming up before the 3p. Hope this helps
