General representation of an element is given as:_Z^A\textrm{X} where,

Z represents Atomic number

A represents Mass number

X represents the symbol of an element

_Z^A\textrm{X}\rightarrow _{Z-2}^{A-4}+_2^4\alpha

As the alpha particle has atomic number of 2 and mass number of 4, this is helium nuclei.
