Size of the Nanoscale | National Nanotechnology Initiative

A strand of human DNA is 2.5 nanometers in diameter. There are 25,400,000 nanometers in one inch. A human hair is approximately 80,000- 100,000 nanometers wide. A single gold atom is about a third of a nanometer in diameter. On a comparative scale, if the diameter of a marble was one nanometer, then diameter of the Earth would be about one meter.

Jul 28, 2016· If we consider a 4 nm diameter gold nanoparticle to be a sphere with a radius of 2nm (remember radius = half of diameter), then its volume is 4/3 πr 3 = 33.5 nm 3. The radius of a sphere is the distance from the edge to the center, 2nm in our example gold nanoparticle; the sphere's volume = 4/3 πr 3 (image adapted from Darkdadaah)

The size of atoms

The Size of Atoms. The size of atoms can be estimated with the use of Avogadro's number along with the atomic mass and bulk density of a solid material. From these, the volume per atom can be determined. The cube root of the volume is an estimate of the diameter of the atom. For carbon, the molar mass is exactly 12, and the density is about 2 ...
