What happens to an atom when it absorbs energy?

Question

1) The atom stores the energy for later use.

2) The atom re-emits the energy as electromagnetic radiation.

3) The extra energy increases the speed of the electrons in their orbitals.

4) The extra energy increases the oscillation frequency of atom's nucleus.

5) none of the above

Answer 1

I don't like any of the answers but 2 comes the closest, I think. What actually happens is that the atom absorbs the energy, electrons move from a lower orbit to a higher orbit THEN (and I emphasize THEN) the electron falls back to a lower level and emits electromagnetic radiation.
