explanation:

the atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons.

because if the tool that you are using is not balanced it there would be false mass.

it is given that trillions of microbes make up to 1% to 3% of the body mass.

average mass per microorganism =
