The Bohr orbit radius for the hydrogen atom $(n = 1)$ is approximately $0.530 \tilde{A}$ . The radius for the first excited state $(n = 2)$ orbit is $(in \tilde{A})$

Options:

Answer:

Solution:

Radius of hydrogen atom $= 0.530 \tilde{A} \dots$ , Number of excited state $(n) = 2$ and atomic number of hydrogen atom $(Z) = 1$ . We know that the Bohr radius. $(r) = \frac{n ^{2}}{Z} \times Radius of atom = \frac{( 2 ) ^{2}}{1} \times 0.530$ $= 4 \times 0.530 = 2.12 \tilde{A} \dots$
