C1 Nuclear Decay, Binding Energy, Mass defect and Mass defect & Binding Energy

Nuclear Decay
-To remove nucleons from the nucleus, work must be done against the strong nuclear force
-Thus, energy is required to separate a nucleus into its constituent neutrons protons

{Binding Energy
Def: Energy required to separate the nucleus into its constituents(nucleons) -OR the energy released when a nucleus is formed from protons & neutrons}
Mass deficit
He nucleus -->2p+2n, =21.007276u+21.008665u=4.031882u, /\m=4.031882u-4.002603u=0.029279u He=4.002603u
-There is a difference between the mass of the nucleus and the sum of the masses of the constituents

{Mass defect
Def: The difference between the measured mass of a nucleus and sum of the masses of its constituents}

Mass Defect & Binding Energy
/\E=c2/\m /\E<--Binding Energy, /\m<--mass deficit
-The mass that is "lost" is converted into energy and when released when nucleons fuse to form a nucleus.
1u=1.6610-27kg, 1u=1.6610-27(3108)2/1061.610-19=933.75MeV, 1u=931.5MeV
-The amount of binding energy for mass defect of 1u equals is 931.5MeV

{Binding energy per nucleon
Def:The binding energy per nucleon is the "average work done per nucleon to remove all the nucleons from a nucleus
-It is a measure of stability of a nucleus
-Higher the binding energy nucleon, the more stable the nucleus
