What happens when an electron gains energy?

• The electron goes to an excited state, and electrons move to an outer shell

• The electron goes to an excited state, and electrons move to an inner shell

• The electron goes to the ground state, and electrons move to an outer shell

• The electron goes to the ground state, and electrons move to an inner shell
