What is the saturated zone

Explanation:

This is the zone in the underground where all the pores in between the soil particles are filled with water. It usually happens when water, after precipitation, seeps below the ground surface and continues to sink underground by gravity. There is a point in the ground where it is completely saturated and this point is referred to as the water table. The water table rises and falls depending on the seasons. It rises during rainy seasons when there is high precipitation and falls in dry seasons when most of the water is lost by capillary action and evaporation on the ground surface.

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.
