A hydrogen atom has an electron in the fundamental state.

a. Show that a radiation with λ = 50 nm will ionize the atom.

b. What will be the excess kinetic energy of the electron in joules?

Round up your answer to the nearest hundredth.

2. Relevant equations

1/lambda= R(1/n^2-1/k^2) (im not sure if this is the equation to be used)

3. The attempt at a solution

1/5x10^-8= 1.097x10^7(1/1^2-1/n^2)

2x10^7=1.097x10^7(1/1^2-1/n^2)

1.823154057=1-1/n^2

.8231540565=1/n^2

1.214839424=n^2

1.1= n

how would this show that atom ionizes?

b. ?
