Distinguish between the ground state and an excited state of an atom

Ground state:                                                                                                      

          This is the state of low energy or we can say that when atom is in ground state then it have lowest energy among the all other states.

Excited state :      

          This is the state of high energy level or we can say that when atom is in excited state then it have high energy then ground level state.

The all atoms exits either in ground state or in exited state.                                                                                                          

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
