It is possible to determine the ionization energy for hydrogen using the Bohr equation. Calculate the ionization energy for an atom of hydrogen, making the assumption that ionization is the transition from n=1 to n=infinity.
I don't know how to solve this problem.

A. -2.18 x 10-18 J
B. +2 .18 x 10-18 J
C. +4.59 x 10-18 J
D. -4.59 x 10-18 J
E. +4.36 x 10-18 J

Please show work and thank you.

• Chemistry -

E = 2.180E-18J x (1/1 - 1/infinity)
But 1/infinity is zero; therefore, E for ionization is E = 2.180E-18 x 1/1 = ?J
