### Clarification on "ground state"

In class today we learned about electrons moving from one energy level to another while also using the terms "ground state" and "excited state"
Dr. Lavelle referred to energy level N=1 as the ground state, but, just to clarify, the ground state is just the energy level an electron is normally in correct?-as in ground state does not refer to N=1?
Sorry I know it's probably a dumb question, but it was just a thought I had.

Well I've learnt this in physics class 3 years ago so I'm not sure I'm right on this, but I think some ground states of e- in atoms might be at N=2,3,etc. It depends on which electron in which atom we're studying at.
About "excited", in the case of H atom: "A hydrogen atom with excess energy is said to be 'excited'".

### Re: Clarification on "ground state"

In today's lecture our professor was talking about one-electron situation that only one electron move around nucleus (ex. Hydrogen atom or carbon ion losing 5 electrons). In the situation like this, the answer to your question is correct and N=1 means equals to ground state. No idea about what will happen if there are more than one electron--sorry
