Question
The ionization energy of hydrogen atom is 13.6 eV. Hydrogen atoms in the ground state are excited by electromagnetic radiation of energy 12.1 eV. How many spectral lines will be emitted by the hydrogen atoms?
Options
A.one
B.two
C.three
D.four
Solution
12.1 eV radiation will excite a hydrogen atom in ground state to n = 3
state number of possible transition = nC2 = 3C2 = 3.
state number of possible transition = nC2 = 3C2 = 3.
