A teacher had two clear liquids, Liquid A and Liquid B. The teacher filled one beaker with Liquid A, and then added Liquid B, drop by drop, until solid crystals suddenly formed on the bottom of the beaker. Which of these is the MOST LIKELY explanation for what happened?

what are the two models

explanation:

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.
