simple molecules vs giant structures
Simple
Carbon dioxide
Uses: Carbon dioxide in solid and in liquid form is used for refrigeration and cooling. It is used as an inert gas in chemical processes, in the storage of carbon powder and in fire extinguishers.
Properties: Carbon dioxide is colorless. At low concentrations the gas is odorless; however, at sufficiently-high concentrations, it has a sharp, acidic odor.
Giant
Diamond
Uses: very hard, strong covalent bonds, does not conduct electricity, all of the electrons are fixed up in the covalent bonds, 4 covalent bonds.
properties: Hardness, heat conductivity, crystal form, index of refraction, specific gravity and dispersion.
Graphite
Uses: Graphite is mostly used for refractory, battery, steel, expanded graphite, brake linings, foundry facings, and lubricants.
properties: It has a high melting point, similar to that of diamond. It has a soft, slippery feel, and is used in pencils and as a dry lubricant for things like locks.conducts electricity. The delocalised electrons are free to move throughout the sheets.
Fullerenes
Properties: High Tensile strength, Good conduct of electricity. The molecule may be a hollow sphere, ellipsoid, tube, or many other shapes and sizes.
Uses: Its molecules are spherical and contain 60 carbon atoms. Fullerenes may be used for drug delivery systems in the body,
A fullerene is an allotrope of carbon whose molecule consists of carbon atoms connected by single and double bonds
Metallic
Uses: Sodium vapor is used in streetlights and produces a brilliant yellow light. Sodium also forms many useful compounds.
The symbol for a sodium ion is Na+1 or Na+. Sodium is an electropositive element with atomic number 11.
Properties: Sodium's melting point is 97.82°C (208.1°F) and its boiling point is 881.4°C (1,618°F). Its density is slightly less than that of water, 0.968 grams per cubic centimeter.
