Uranium is a very heavy metal which can be used as an abundant source of concentrated energy.
Uranium occurs in most rocks in concentrations of 2 to 4 parts per million and is as common in the Earth's crust as tin, tungsten and molybdenum. Uranium occurs in seawater, and can be recovered from the oceans.
Uranium was discovered in 1789 by Martin Klaproth, a German chemist, in the mineral called pitchblende. It was named after the planet Uranus, which had been discovered eight years earlier.
Uranium was apparently formed in supernova about 6.6 billion years ago. While it is not common in the solar system, today its slow radioactive decay provides the main source of heat inside the Earth, causing convection and continental drift.
The high density of uranium means that it also finds uses in the keels of yachts and as counterweights for aircraft control surfaces, as well as for radiation shielding.
Uranium has a melting point is 1132°C. The chemical symbol U. World Nuclear Association
"You thus have uranium in your blood cells and tissues, strontium and calcium in your bone marrow, and other radioactively liberated particles affecting every part of your body, its genes, hormones and even unto the destruction of the proteins of your hair and nails, all confined within one particle."
