Question

What is the radius of the 5th orbital in hydrogen?

Answer 1

`\\ \rm\Rrightarrow r=0.529(n^2)/(Z^2)`

• For hydrogen Z=1

`\\ \rm\Rrightarrow r=0.529(5)²`

`\\ \rm\Rrightarrow r=0.529(25)`

`\\ \rm\Rrightarrow r=1.3225nm`

Answer 2

So, the radius of fifth Bohr orbital of hydrogen is 1. 3225 nm.
