Concept explainers
To show:
The magnitude of the electrostatic potential energy of an electron in a hydrogen atom is twice the magnitude of its kinetic energy.
Answer to Problem 62P
Solution:
The magnitude of the electrostatic potential energy of an electron in a hydrogen atom is twice the magnitude of its kinetic energy.
Explanation of Solution
Calculation:
The expression for the potential energy of an electron in a hydrogen atom can be given as:
_____________________________________________(1)
Where, k is Coulombs constant
Z is the atomic number, that is 1
e is the charge of electron
and, r is the radius of Bohr orbit
the electrostatic force of attraction between the nucleus and the revolving electron is equal the the centrifugal force, the relation can be written as:
Or we can say that
