Q. Consider the following radioactive decay process
${ }_{84}^{218} A \xrightarrow{\alpha} A_1 \xrightarrow{\beta^{-}}A_2 \xrightarrow{\gamma} A_3 \xrightarrow{\alpha} A_4 \xrightarrow{\beta^{+}} A_5 \xrightarrow{\gamma}A_6$
The mass number and the atomic number of $A_6$ are given by:

Solution:

$ { }_{84}^{218} A \stackrel{\alpha}{\longrightarrow}{ }_{82}^{214} A _1 \stackrel{\beta^{-}}{\longrightarrow}{ }_{83}^{214} A _2 \stackrel{\gamma}{\longrightarrow}{ }_{83}^{214} A _3 $
${ }_{83}^{214} A _3 \stackrel{\alpha}{\longrightarrow}{ }_{81}^{210} A _4 \stackrel{\beta^{+}}{\longrightarrow}{ }_{80}^{210} A _5 \stackrel{\gamma}{\longrightarrow}{ }_{80}^{210} A _6$
