Question
How has Bohr’s theory helped in calculating the energy of hydrogen electror in the ground state and also in the excited state?
Solution
The energy of hydrogen electron is
where m = mass of electron
e = charge on electron
h = Planck's constant
n = integer with value, 1, 2, 3, 4, etc.
By substituting the values, we have,
By assigning different values to the energy of hydrogen electron in ground state and different excited states can be calculated.
From the above table, it is obvious that negative value of energy keeps on decreasing as the electron moves from ground state to the higher energy states.
