For this question, we have to find the ionization, but at first we should try to recall what desire organization means. Ionization means, like removing an electron, are a more terms with that coincide with physics. It is raising the electron 20 level energy go. So if we just write it in the form of equation e ionization, the final energy zero. Since it's raised to the zero emission energy level on, then we have e n the energy level of the end state on. We can then read serial mine US 13.6 electron balls by end square by using the formula, PTA and energy off the end state. So if we just plug in the value for M, we get, there should be a negative sign. Here we get that the value is 1.51 electron balls.
