Question

Example 12.3 It is found experimentally that 13.6 eV energy is
required to separate a hydrogen atom into a proton and an electron.
Compute the orbital radius and the velocity of the electron in a
hydrogen atom​

Answer 1

Step-by-step explanation:

If 13.6eV energy is required to separate a hydrogen atom into a proton and an electron, then the orbital radius of electron in a hydrogen atom is. ∴ As orbital radius, r=-e28πε0E=9×109×(1.6×10-19)22×(2.2×10-18)=5.3×10-11m.
