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.

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. We do as follows: diameter = 2 x 1.35 x10^ -10 m ( 1000 mm / 1 m ) = 2.7 x 10^-10 mm / atom Number of gold atoms = 8.5 mm / 2.7 x 10^-10 mm / atom = 31481481481.481 atoms
