Calculate the percentage of magnesium in magnesium oxide using the following data: mass of magnesium = 24 g mass of magnesium oxide = 40g if u could can u plz answer asap its for another test

h let me think

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.
