An electron in a sodium atom gains enough energy to move from the second shell to the third shell. The sodium atom becomes:
(1) a positive ion
(2) a negative ion
(3) an atom in an excited state
(4) an atom in the ground state

(3) The atom goes into an excited state.

I say this because since it's moving from the second level to the third, it gains more energy. And it can't be an ion because there are electrons still present in the atom. If the electrons had happened to be removed then it would have been a negative ion.

Answer;

-(3) an atom in an excited state

Explanation;

-An electron in a sodium atom gains enough energy to move from the second shell to the third shell. The sodium atom becomes an atom in an excited state.

-Ground state is the lowest allowable energy state of an atom. When electrons are subjected to stimuli like heat, light or electricity an electron may jump to a higher energy level, which is the excited state. Excitation is the elevation in energy level above the baseline energy state.
