Calculate the binding energy for .(1)H^(...

Calculate the binding energy for `._(1)H^(2)` atom. The mass of `._(1)H^(2)` atom is 2.014102 amu where `1n` and `1p` have their weights 2.016490 amu. Neglect mass of electron.

Text Solution

Verified by Experts

Mass of neutron and proton in `._(1)H^(2) = 2.016490 "amu"`
Actual mass of `._(1)H^(2) = 2.014102 "amu"`
`:. (Delta m)` mass defect `= 2.388 xx 10^(-3) "amu"`
`(2.016490 - 2.014102) "amu"`
`:.` Binding energy `= 2.388 xx 10^(-3) xx 931.478 MeV`
`= 2.2243 MeV`
