Nuclei NEET MCQs Formulae

Before attempting these MCQs, first read the Nuclei notes here: Nuclei Physics Notes.

Nuclear RadiusR = R0 A^(1/3), where R0 is about 1.2 fm.

Nuclear Densityrho = nuclear mass / nuclear volume, nearly constant for all nuclei.

Mass DefectDelta m = Z mp + (A - Z) mn - M nucleus.

Binding EnergyB.E. = Delta m c^2 = Delta m(in u) x 931.5 MeV.

Binding Energy Per NucleonB.E./A decides relative stability of nuclei.

Radioactive Decay LawN = N0 e^(-lambda t), and activity A = A0 e^(-lambda t).

Half-LifeT1/2 = 0.693 / lambda.

Mean Lifetau = 1 / lambda = T1/2 / 0.693.

ActivityA = lambda N, measured in becquerel or curie.

Alpha DecayMass number decreases by 4 and atomic number decreases by 2.

Beta Minus DecayAtomic number increases by 1; mass number remains unchanged.

Beta Plus DecayAtomic number decreases by 1; mass number remains unchanged.

Gamma DecayNo change in A or Z; the nucleus loses excitation energy.

Q ValueQ = (mass of reactants - mass of products)c^2.

FissionHeavy nucleus splits into medium nuclei with energy release.

FusionLight nuclei combine; high temperature helps overcome Coulomb repulsion.
