Question

How much of energy will be released when the electron shifts from
second orbit to first orbit of He+ ion? What will be the radius of its 1st
orbit?

Answer 1

Answer:

Energy is emitted from the atom when the electron jumps from one orbit to another closer to the nucleus. Shown here is the first Balmer transition, in which an electron jumps from orbit n = 3 to orbit n = 2, producing a photon of red light with an energy of 1.89 eV and a wavelength of 656 nanometres......
