Accepted Answer
To move an electron from ground state to the fourth excited state, you would need to add energy equal to 0.5×10^-18 Joules per electronThe first excited state has a lower bound of 2.00 ev, and the second excited state has a lower bound of 3.20 ev. To move an electron from the ground state to one of these higher-energy states, you would need to add energy equal to 1.36/2 = 0.52 ev per electron, or 6 x 10^-18 Joules per electron. To move an electron from ground state to the fourth excited state, you would need to add energy equal to 1 - 2(1/2) = 0.5 x 10^-18 Joules per electron, or 5 x 10^-21 J/electron.To learn more about excited state visit: https://brainly.com/question/15413578#SPJ4
