Question

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

Answer 1

Let's see

According to bohrs model

`\\ \rm\Rrightarrow r\propto n^2/Z^2`

`\\ \rm\Rrightarrow r= r_on^2/Z^2`

`\\ \rm\Rrightarrow r=0.529* (5^2)/(1^2)`

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

`\\ \rm\Rrightarrow r=1.32nm`

Answer 2

Answer:the radius of fifth Bohr orbital of hydrogen is 1.3225x10^-9
