Radioactive emission

The emission of radiation from an atom will change its nature.

Nuclear equations show the products of nuclear decay.

In nuclear equations, the sum of the atomic number and mass number on each side of the equation should balance.

Alpha emissions

_{\,\,90}^{232}Th \to _{\,\,88}^{228}Ra + _2^4He_{}^{2 + }

_{\,\,90}^{232}Th \to _{\,\,88}^{228}Ra + \alpha

Beta emissions

_{\,\,6}^{14}C \to _{\,\,7}^{14}N + _{ - 1}^{\,\,\,0}e_{}^ -

_{\,\,6}^{14}C \to _{\,\,7}^{14}N + \beta
