List of top Physics Questions on Nuclei asked in NEET (UG)

If a ^b aX species emits firstly a positron, then two α and two β and at last one α is also after intially it fainally convets into stable ^c dY species so correct relation will be

X(n, α) 7/3Li , then X will be

The half-life of a radioactive isotope is 3 h. If the initial mass of the isotope was 300 g, the mass which remained undecayed after 18 h would be

The relation between  \(λ\) and \(T_\frac 12\)is: 
\((T_\frac 12 = half\  life, \ λ→decay\  constant)\)

Nuclear–Fission is best explained by:

India has the world's largest deposits of thorium in the form of

The mass of $\alpha$-particle is

The energy equivalent of one atomic mass unit is
