Draw the Lewis structures of the reactants Determine the total energy of the bonds broken in the reactants
Draw the Lewis structures of the products
Determine the total energy of the bonds formed in the products
Calculate the enthalpy (ΔH°) for the reaction
Is this exothermic or endothermic?

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.
