Vedclass · Answer

(D) The correct answer is $D$.Natural radioactive decay processes include alpha decay, beta decay, and gamma decay.$1$. In alpha decay, the nucleus emits an alpha particle, which is a helium nucleus $({ }_2 He ^4)$.$2$. In beta decay, the nucleus emits electrons ($\beta^{-}$ decay) or positrons ($\beta^{+}$ decay).$3$. In gamma decay, the nucleus emits high-energy photons, which are electromagnetic radiations.Neutrons are not emitted during standard natural radioactive disintegration processes.
