for this exercise have a hydrogen atom initially at the second energy level and equals two. And we have to calculate what is the energy necessary in order to ah, ionized? Is that Adam? So in order to do that, let's calculate what is the energy of the second energy level that will be minus 13.6. That's the energy of the ground state over two square, which is four. And I've been votes. This is minus 3.4 eloquent votes and the in order to ionized the Adam, the total energy of the Adam has to be at least zero. So the minimum energy you have to give the Adam to join eyes it, it's gonna be 3.4 electoral votes so that when you some 3.4 with minus really went for, you have zero
