What is the distance of separation between 3rd and 4th orbit of H-atom

1.	What is the distance of separation between 3rd and 4th orbit of H-atom?
Answer» Distance of 3^rd orbit d₃ = \(\frac{52.9\times n^2}{z}\) = \(\frac{52.9\times(3)^2}{1}\) = 476.1 pm Distance of 2^nd orbit d₂ = \(\frac{52.9\times n^2}{z}\) = \(\frac{52.9\times(2)^2}{1}\) = 211.6 pm \(\therefore\) Distance of separation between 3^rd and 4^th orbit of H-atom = Distance of 3^rd orbit – Distance of 2^nd orbit from the nucleus = 476.1 − 211.6 = 264.5 pm

What is the distance of separation between 3rd and 4th orbit of H-atom?

Answer»

Distance of 3^rd orbit

d₃ = \(\frac{52.9\times n^2}{z}\)

= \(\frac{52.9\times(3)^2}{1}\)

= 476.1 pm

Distance of 2^nd orbit

d₂ = \(\frac{52.9\times n^2}{z}\)

= \(\frac{52.9\times(2)^2}{1}\)

= 211.6 pm

\(\therefore\) Distance of separation between 3^rd and 4^th orbit of H-atom

= Distance of 3^rd orbit – Distance of 2^nd orbit from the nucleus

= 476.1 − 211.6

= 264.5 pm
