Atomic Structure

The energy of the electron in the hydrogen atom is given by the formula: where is the principal quantum number. For Li, the ionization energy for the first electron transition is given. The energy associated with the second excited state of Li corresponds to the energy required to move from the first energy level to the second excited state . Now using the above formula, we calculate the energy for the second excited state: Now converting this to Joules: Thus, the energy associated with the second excited state of Li is .
