Question
The ionization enthalpy of hydrogen atom is 1.312 × 106 Jmol-1. The energy required to excite the electron in the atom from n = 1 to n = 2 is
Options
A.8.51 × 105 j mol-1
B.6.56 × 105 j mol-1
C.7.56 × 105 j mol-1
D.9.84 × 105 j mol-1
Solution
ᐃE = E2 - E1 = - 
= 9.84 × 105 J mol-1
= 9.84 × 105 J mol-1
