Vedclass · Answer

(B) The energy state nearest to the nucleus is the ground state,which corresponds to $n = 1$. When an electron moves from a lower energy level $(n = 1)$ to a higher energy level $(n = 3)$,it must gain energy. According to Planck's quantum theory,the energy is absorbed in the form of discrete packets called quanta. Since the transition involves a change in energy levels,the electron absorbs one quantum of energy corresponding to the difference between the two levels,$\Delta E = E_3 - E_1$.

When the electron passes from the energy state nearest to the nucleus to the third energy level,it will:
