### How to Calculate the Volume of an Atom | Sciencing

Mar 13, 2018· The calculation of the volume of an atom is based on a simplistic understanding of an atom as a sphere. Whenever you are asked to calculate the volume of an atom, assume it is a sphere, but be aware that an atom is much more complex than a simple sphere as explained by the theories of quantum mechanics. ### the radius of a gold atom is 1.35 angstroms. how many gold ...

Dec 21, 2016· The angstrom, also known as the angstrom unit, is a measure of displacement equal to 0.0000000001 meter (10 -10 m). It would be helpful to convert the units of angstrom to mm.
