A radioactive nucleus undergoes a series of decay according to the scheme

\(A \xrightarrow{\alpha} A_1 \xrightarrow{\beta} A_2 \xrightarrow{\alpha} A_3 \xrightarrow{\gamma} A_4\)

If the mass number and atomic number of \( A \) are 180 and 72 respectively, then what are these number for \( A_{3} \)
