Let \(L_1\) and \(L_2\) be the orbital angular momentum of an electron in the first and second excited states of the hydrogen atom, respectively. According to Bohr's model, the ratio \(L_1:L_2\) is:
For which one of the following Bohr model is not valid?
1. Singly ionised helium atom
2. Deuteron atom
3. Singly ionised neon atom
4. Hydrogen atom
The total energy of an electron in the stationary orbit of the hydrogen atom can be obtained by:
