The time period of the electron in the ground state of the hydrogen atom is two times the time period of the electron in the first excited state of a certain hydrogen-like atom (atomic number Z). The value of Z is

Options:

Answer:

Solution:

$T \propto n^{3} / Z^{2}$ . $T_{H} (n = 1) = 2 T_{X} (n = 2) \Rightarrow 1 = 2 \times \frac{8}{Z ^{2}} \Rightarrow Z^{2} = 16 \Rightarrow Z = 4$ .
