Answer:
α or He⁴₂
Explanation:
*The computer does not allow for the 4 and 2 to be directly inline
The alpha particle can be notated as a simple "α". Since that symbol is the letter alpha in Greek. Another way of notating the particle is "He⁴₂" (where the 2 is directly under the 4), this is because an alpha particle contains the exact same components of a helium nucleus, two protons, and two neutrons (with an atomic mass of four).
