2009-6-27 I get that I need to find the number of atoms of gold in 1 cm, therefore, it should be the cube root of 5.9 x10^22, which I have as roughly 3.89 x 10^7 atoms/cm. From here, I divided 1 by the above result to get the diameter, and got 2.6 Angstroms diameter. The book's answer key gives the answer as a range of 2.6 to 6.8 angstroms.

MoreAn 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 × 10 −10 m to 5 × 10 −10 m).

MoreOne measure of size is the element-element distance within the element. It is not always easy to make sensible comparisons between the elements however as some bonds are quite short because of multiple bonding (for instance the O=O distance in O 2 is short because of the the double bond connecting the two atoms. The bond length in AgAg is: 288.9pm. ...
