Given the atomic radius of xenon, 1.3 ? , and knowing that a sphere has a volume of 4? r3/3, calculate the fraction of space that xe atoms occupy in a sample of xenon at stp.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
