Question

The radius of the Bohr orbit in the ground state of hydrogen atom is 0.5 Å. The radius o fthe orbit of the electron in the third excited state of He^(+) will be

Answer 1

Answer:

$radius \: of \: hydrogen \: = 0.529 \times \frac{ {n}^{2} }{z} \\ radius \: = 0.529 \times \frac{9}{2} \\ radius \: = 2.4$
