Question

(e) If the radius of the first orbit of hydro-|
gen atom is 5.3x10-11 m what is the radius of the third orbit? ​

Answer 1

Answer:

4.77×10^-10 m

Explanation:

Formula for the radius of orbit is r = r0 •n^2

when n =2

5.3×10^-11×3^2

47.7×10^-11 m

4.77×10^-10 m

Answer 2

Answer:

Radius of orbit is r = r0• n²

when n = 2

5.3*10^-11*3^2

47.7*10^-11m

4.77*10^-10m

Explanation:

Hope it helps you have a great day :-))
