Chemistry: Featured Facts
Uses Of Hydrocarbons
Chemistry / Elements and Compounds

The hydrocarbons are the most broadly used organic compounds known, and are quite literally the driving force of western civilization. The greatest amounts of hydrocarbons are used as fuel for combust continue reading this fact

What Is A Half-life?
Chemistry / Elements and Compounds

Natural uranium contains 99% U238 and only about 0.7% U 235 by weight. When isotopes break down, or decay, they usually split apart into two smaller atoms. Excess neutrons and protons are often sent flying off through space, taking the excess energy of the atoms with the continue reading this fact

Carbon Dating
Chemistry / Chemical Properties

Scientists date fossils by measuring carbon. As isotopes break down, or decay they give off radiation. Materials that decompose in this way are said to have a 'half-life'. As the quantity of material present decreases, so does the actual rate at continue reading this fact
