### Calculating Ionization Energy

Posted:

**Fri Nov 01, 2019 1:44 pm**In my discussion we did a problem that was essentially the following:

Calculate the ionization energy of RB given that a radiation with the wavelength of 58.4nm produces electrons with a velocity of 240km/s, when it hits RB.

Why do we solve for the work function?
