Having the mass and the volume of the element will useful.
Find the number of mole of the given element, = mass / molar mass
Use the no of mole to find the number of atoms in that given element, Number of atoms = no of mole x 6.02 x10^23
Now divide the volume of the given element with the number no of atoms.
This will produce the value of volume of an atom
Assuming the atom is in sphere shape,
4/3(22/7)r^3 = volume of ant atom
diameter is 2xr where r is the atomic radius
In this case the element shud be made up of monoatons. If it is a diatomic, then multiply the number of partilces by 2 and then proceed

An atom is one of the basic units of matter. Everything around us is made up of atoms. An atom is a million times smaller than the thickest human hair. The diameter of an atom ranges from about 0.1 to 0.5 nanometers (1 Ã 10-10 m to 5 Ã 10-10 m).

It doesn't really have one, an atom is simply an atomic nucleus, with a bunch of electrons that just sort of hang out in the neighborhood. But the atomic spacing takes definite values in a crystal, so if you measure the density, know the chemical composition, and can remember Avogadro's number [6E23 molecules per mole], you can easily compute the spacing.

The easiest way is to take a crystal and run x-rays through it and measure the defraction of the x-rays.
