Question

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.

Answer 1

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
