Respuesta :

Can't find the options on the keyboard so ill try to describe it. I think either an He symbol or the greek letter alpha is accepted. There must be a 4 at the top left and a 2 at bottom left. 

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).
