Question

Calculate the radius of Bohrs fifth orbit of helium atom

Answer 1

Answer:

The answer is 1.3225 nm

Explanation:

The formula for calculating radius of the nth orbit of the hydrogen atom is.

r = 0.0529 nm(n2)

Here n is the orbit number.

r = 0.0529nm x (5)2

r = 0.0529 x 25

r = 1.3225 nm

Answer 2

Answer:

For fifth orbit, the radius is r5=0. 0529×52 nm=1.
