Which particle can be used to change $_{13}Al^{27}$ into $_{15}P^{30}$?

What is $X$ in the following reaction?
${}_{12}Mg^{26} + {}_{1}H^{2} \longrightarrow {}_{12}Mg^{27} + X$

An element $_{96}X^{227}$ emits $4\alpha$ and $5\beta$ particles to form a new element $Y$. The atomic number and mass number of $Y$ are:

The first artificial disintegration of an atomic nucleus was achieved by

Identify $X$ in $_{16}S^{32} + X \to _{15}P^{30} + _{2}He^{4}$.

Artificial elements have been prepared by bombardment reactions in high energy accelerators. What is the mass number of the element $X$ produced in the following nuclear reaction: $_{95}^{249}Cf + _{7}^{15}N \rightarrow _{105}X + 4_{0}^{1}n$?
