Vedclass · Answer

(N/A) When a proton and an electron combine to form a $H$-atom,the system moves to a state of lower potential energy to attain maximum stability. According to Einstein's mass-energy equivalence principle,$E = mc^2$,this reduction in potential energy corresponds to a decrease in the mass of the system. This mass defect is released as energy (binding energy) during the formation of the atom. Consequently,the mass of the $H$-atom is less than the sum of the masses of its constituent particles in their free state.

The mass of a $H$-atom is less than the sum of the masses of a proton and an electron. Why is this?
