Question

A hydrogen atom consists of one electron and one proton bound together. The binding energy is 13.6 eV, where 1 eV = 1.6 x 10 -19 Joules. The mass of a separate mass of a proton and an electron may be found in many sources. Calculate the difference in mass between a hydrogen atom and the combination of the mass of an electron plus a proton. This means that the potential energy of binding two objects together weighs something itself. For instance, the gravitational potential energy responsible for the binding of the earth and moon together in their mutual orbits has mass associated with it.

Can someone please work me through this?

Explanation / Answer

Binding energy = mass defect * 931.5 Mev

13.6 = delta M * 931.5

delta M = 13.6/931.5

delta M = 14600 amu
