Astatine

Attenborough Nature Reserve was established in 1966 and opened by Sir David Attenborough. The reserve is best known for its birds.

The area is an important site for winter wildfowl and often holds a high proportion of the county's shoveler and diving ducks, with larger numbers of mallard, teal, and occasionally wigeon.

Scarcer wildfowl such as sawbills and sea ducks are recorded regularly and cormorants are common. All the British grebes have been recorded. In the spring and autumn, many migrants birds pass through and the Delta area attracts a wide range of waders in small numbers including the iconic bittern.

Attenborough is also a village and a suburb in the Broxtowe borough. It forms part of Greater Nottingham, and is to the southwest of the city of Nottingham, between Long Eaton and Beeston.

Henry Ireton, one of the most senior Parliamentarians in both military and political matters and who married one of Oliver Cromwell's daughters, was born here. 

This unstable hallogen wasn't discovered until 1940 and was once believed to be the rarest element on Earth.

It was discovered in 1940 by Dale Corson, Kenneth McKenzie, and Emilio Segre at Berkley. It wasn't until three years later, however, that astatine was found in nature.
