Me with 5 questions that would be nice. which pair of elements are the most common found in the sun? a. helium and oxygen b. carbon and hydrogen c. hydrogen and helium d. helium and oxygen

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.
