1.	An electron in an hydrogen atom has exited from n=1to n=3 orbit, then
Answer» When an electron jumps from from one orbitals to ANOTHER orbital the energy ABSORBED or released is given by, hν=E n 3 −E n 1 Now, E n = n 2 −13.6 eVE n 1 =−13.6eV and E n 3 =−1.5eVTherefore, hν=12.1eVHence, 12.1eV amount of energy is absorbed during transition from first orbitals in third orbital.Explanation:please mark me brainlist
