Question

Calculate the ratio of radius of 2nd Bohr orbit of Het ion
and 2nd Bohr orbit of Be+3​

Answer 1

Explanation:

3 : 2. B.

9 : 4. C.

2 : 3. D.

4 : 9. EASY. Share. Study later. Answer. 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. Hence, option D is correct. Answer By Toppr. Share. How satisfied are you with the answer?

Answer 2

Answer:

We know that the radius of an orbit in a hydrogen atom is directly proportional to nXn .

Therefore, the ratio of the radius of 2 nd

orbit to the radius of 3 rd orbit = 3X3/2X2

=9/4
