The ionization energy of the electron in the hydrogen atom

Home » Modern Physics » Atoms » Question

The ionization energy of the electron in the hydrogen atom in its ground state is 13.6 eV. The atoms are excited to higher energy levels to emit radiations of 6 wavelengths. Maximum wavelength of emitted radiation corresponds to the transition between

1. n = 3 to n = 1 states
2. n = 2 to n = 1 states
3. n = 4 to n = 3 states
4. n = 3 to n = 2 states

Correct Option: C

	n(n - 1)	= 6
	2

n² – n – 12 = 0
(n – 4) (n + 3) = 0 or n = 4
