Question

Ratio of radii of second and fourth orbit in H-atom

Answer 1

Explanation:

We know that the radius of an orbit in a hydrogen atom is directly proportional to n2. Therefore, the ratio of the radius of 2nd orbit to the radius of 3rd orbit =3222=94.

Answer 2

H is hydrogen

Hidrogen have only 1 electron and so only 1 orbit.

There's no question of 2nd and 4th orbit.
