Question 11 Mark
A radioactive nucleus undergoes a series of decays as per following scheme :
$A \xrightarrow{(\alpha)} A _1 \xrightarrow{(\beta)} A _2 \xrightarrow{(\beta)} A _3$.
The atomic number and mass number of Nuclei 'Á' are 92 and 238 respectively then what are these numbers for A3.
$A \xrightarrow{(\alpha)} A _1 \xrightarrow{(\beta)} A _2 \xrightarrow{(\beta)} A _3$.
