Uranium gets its name from Uranus, the Greek god of the sky. It is a silvery-white metallic element that is 65% more dense than lead and is a little softer than steel. It is believed that uranium was formed in a supernova about 6.6 billion years ago and is the main source of heat inside the Earth. It also occurs naturally in low concentrations in soil, rock, and water. Commercial mining of uranium occurs in areas where uranium is present in high concentrations. Most uranium is currently mined in Canada, Australia, Kazakhstan, Namibia, Niger, and Russia.
In the next segment I will discuss the discovery of uranium and why the properties of this element are so special.
