Detailed Solution
Download Solution PDFGiven:
The radius of innermost orbit of a hydrogen atom \(r_0=5.3\times10^{-11}m\)
Let \(r_2 \) be the radius of the orbit at n=2.
Concept:
The radius of outermost orbit of a hydrogen atom is given as
- \(r_{n}=n^2r_0\)
Explanation:
The radius in orbit n=2 can be find out as,
\(r_{n}=n^2r_0\)
\(r_2=(2)^2r_0\)
\(r_2=4\times5.3\times10^{-11}\)
\(r_2=21.2\times10^{-11}m=2.12\times10^{-10}m\)
Hence, the correct answer is Option-2- \(r_2=2.12\times10^{-10}m\).
