Your science teacher gives you three liquids to pour into a jar. after pouring, the liquids layer as seen here. what property of matter allows the different liquids to layer in the jar?
a) color
b) density
c) mass
d) texture

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.
