Uranium: the essentials

Uranium atoms have 92 electrons and the shell structure is 2.8.18.32.21.9.2. The ground state electronic configuration of neutral uranium is [Rn].5f3.6d1.7s2 and the term symbol of uranium is 5L6.

Uranium: description  

Uranium is of great interest because of its application to nuclear power and nuclear weapons. Uranium contamination is an emotive environmental problem. It is not particularly rare and is more common than beryllium or tungsten for instance.

Uranium gives interesting yellow and green colours and fluorescence effects when included to glass in conjunction with other additives. The image below is an English amphora dating to about 1930 showing a characteristic yellow-green colour. The image is reproduced with the permission of Ken Tomabechi (Uranium Glass Gallery in Japan), where you can find further information about uranium glass. This type of glass is sometimes referred to as "vaseline glass" in the UK and USA and as "Annagelb" (yellow) or "Annagruen" (green) in Germany.
