Question

the radius of fifth bohr orbit in hydrogen atom is​

Answer 1

Explanation:

here n(orbital)=5

z(at.no.)=1

Answer 2

To Find :

The radius of fifth Bohr orbit in hydrogen atom .

Solution :

We know , radius in n orbit of hydrogen atom is given by :

$r_n=n^2\times 0.53\ \AA$

Here , n is the number of bohr orbit .

So , for fifth bohr orbit n = 5 , radius is given by :

$r_5=5^2\times 0.53\ \AA\\\\r_5=13.25 \ \AA$

Therefore , radius of fifth bohr orbit in hydrogen atom is​ $13.25\ \AA$ or $1.325\times 10^{-9}\ m$ .
