Estimate the difference in energy between first and second Bohr orbit for ahydrogen atom. At what minimum atomic number, a transition from n=2 to n=1 energy level would result in the emission of X-rays with lamda=3.0 xx 10^(-8) m?Which hydrogen-atom like species does this atomic number correspond to? |

Answer» Solution :Apply `Delta E = RchZ^2 ((1)/(n_1^2) - (1)/(n_2^2)) ` `1.63 xx 10^(-11) ERG, Z = 2, He^+` |
