Why you will never see a physical sample of astatine
Astatine is one of the rarest elements on Earth. This video explores the extreme properties that make it nearly impossible for chemists to handle, featuring Professor Sir Martyn Poliakoff.
Astatine is characterized by intense radioactivity and an incredibly short half-life. These physical properties mean that the element is rarely encountered by chemists in a laboratory setting. Because of this volatility, the video does not feature a visible sample of the element itself.
Produced by the Royal Society of Chemistry, the presentation delves into the unique uses and properties of this elusive element, providing insight into why it remains such a challenge to study.
