अणुकेंद्रका भोवती दुसऱ्या भ्रमणकक्षेत भ्रमण करणाऱ्या इलेक्ट्रॉनची ऊर्जा - 3.4 eV आहे. त्याची तिसऱ्या भ्रमण कक्षेत ऊर्जा किती ? Energy of the electron revolving around the nucleus in second orbit is - 3.4 eV. What is its energy in third orbit ?
1)-1.51 J
2)-3.4 eV
3)-1.51 eV✓ Correct
4)-13.6 eV
Energy in the nth orbit of a hydrogen-like atom is given by E_n = -13.6 / n² eV. For n=3, E3 = -13.6 / 9 = -1.51 eV.
