Consider the reaction of a starting material A to form a product B. What is the percent yield of B in a reaction that uses 26.3 g of starting material A, has a theoretical yield of 19.9 g of B, and an actual yield of 15.4 g of B? show steps

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.
