Question

How do i know whether or not an atom is in ground state, excited state or an ion. Put it in simple terms, I beg of you

Answer 1

Since you ask so nicely! (-:
If the number of electrons = number of protons, it is an atom not an ion.
If the electronic config of the atom is where all the electrons are occupying the lowest energy level, then the atom is in the ground state. If the electrons are in higher energy levels then the atom is in an excited state.
