If the components of a liquid hydrocarbon are to be separated by fractional distillation, the components should have A. Large differences between their boiling points
B. Very small differences between their boiling points
C. Large differences between their freezing points
D. Very small differences between their freezing points

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.
