Question

The energy associated with the first orbit in the hydrogen atom is -2.18 x 10^-18 J atom^-1. What is the energy associated with the fifth orbit?

Answer 1

Energy of the first orbit in a H atom = -2.18 x 10^-18 J atom^-1

Energy of the 5th orbit in a H atom = -{2.17 x 10^-18 J atom^-1}/{(5)²}

= -8.72 x 10^-10 J atom^-1
