$$\alpha^{4}_{2} = Alpha particle $$

greatlife44 · Answer

$$\alpha ^{mass number}_{atomic number}$$

greatlife44 · Answer

top number 4 is our mass number protons+neutrons 
while the bottom number is our atomic number protons. 

when an alpha particle is released, it's usually for heavier nuclei, i.e. there's just too much of everything.
