Given below are densities of some solids and liquids. Give rough estimates of the size of their atoms:

[Hint: Assume the atoms to be ‘tightly packed’ in a solid or liquid phase, and use the known value of Avogadro’s number. You should, however, not take the actual numbers you obtain for various atomic sizes too literally. Because of the crudeness of the tight packing approximation, the results only indicate that atomic sizes are in the range of a few .

If is the radius of the atom then the volume of each atom will be

Volume of all the substance will be

atomic mass of the substance

density of the substance

We know, One mole of the substance has atoms

For carbon, and

For gold, and

For lithium, and

For nitrogen (liquid), and

For fluorine (liquid), and
