Scientists are working with a liquid that is made of only one type of atom. Which statement correctly describes this liquid? A)The liquid contains only one compound. B)The liquid contains only one element. C)The liquid contains only neutral electrons. D)The liquid can be broken down into simpler substances.

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.
