Question

calculate the ionisation energy of hydrogen atom using bohr's theory

Answer 1

Answer:

n2 is the principle quantum number of the higher energy level. Since the electron is in the n1=1 ground state we need to consider series 1. These transitions occur in the u.v part of the spectrum and is known as The Lyman Series. You can see that as the value of n2 increases then the value of 1/(n2)^2 decreases.

Answer 2

Answer:

For the ionization energy of hydrogen, it means that n (initial) is 1 and n (final) is infinity. Substitute those 2 values into Bohr equation to get 2 values. (1 over infinity = 0) Then the difference of the 2 values is the ionization energy for 1 hydrogen atom.
