The mass of product that can be formed from reactant A is 45.6 g, and the mass of product that can be formed from reactant B is 33.2 g. Is reactant A or B the limiting reactant? A.) Reactant B
B.) Both
C.) Neither
D.) Reactant A

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
