(B) When a radioactive nucleus emits an $\alpha$-particle $(_{2}He^{4})$,the atomic number $Z$ of the nucleus decreases by $2$ and the mass number $A$ decreases by $4$.The decay equation is given by: $_{Z}X^{A} \rightarrow _{Z-2}Y^{A-4} + _{2}He^{4}$.Since the atomic number $Z$ decreases by $2$,the element shifts two places to the left in the periodic table.
