# NEET Physics Nuclei Questions Solved

NEET - 2009

In the nuclear decay given below

the particles emitted in the sequence are

(a)                               (b)

(c)                                (d)

Key Idea In a nuclear reaction conservation of charge number and mass number must hold good.

Alpha particles are positively charged particles with charge +2e and mass 4m. Emission of an $\mathrm{\alpha }$-particle reduces the mass of the radionuclide by 4 and its atomic number by 2. $\mathrm{\beta }$-particles are negatively charged particles with rest mass as well as charge same as that of electrons. $\mathrm{\gamma }$-particles carry no charge and mass.

Radioactive transition will be as follows
