In ground state of He⊕ ion how much energy is supplied to electron so that second line of balmer series is obtained in its spectrum:- (a)10.2eV (b)48.36eV (c)51eV (d)None of thesePlease give the explanation. |

Answer» E = 13.6 * (1/ni^2 -1/nf^2) * z^2 eV z = 2 ( atomic no. of Helium) For Balmer series; ni = 2 and nf = 4 (i.e. second line of balmer series) E = 13.6 * (1/2^2 -1/4^2) * z^2 eV. E = 10.2 eV. |
