Energy of an electron in the nth orbit of hydrogen atom is given by E,- ev. How much energy is required to take an electron from the ground state to the first excited state?

Answer»

Solution :In HYDROGNE atoms groundstatecorrepondsto N = 1AND the firstexcited state corresponds to n = 2. HENCE, energyrequired .
`E = E_(2)- E_(1) = (-13.6)/((2)^(2))-[(-13.6)/((1)^(2))] = - 3.4+13.6 = +10.2 eV`
