Question

The radius of an atom of gold (Au) is about 1.35 Å. (a) Express this distance in nanometers (nm) and in picometers (pm). (b) How many gold atoms would have to be lined up to span 1.0 mm? (c) If the atom is assumed to be a sphere, what is the volume in cm³ of a single Au atom?

Step 1

1 angstrom = 0.1 nanometers 1 angstrom = 100 picometers Therefore, the radius of the gold atom in nanometers = 1.35 * 0.1 = 0.135 nm And the radius of the gold atom in picometers = 1.35 * 100 = 135 pm Show more…
