72 views
The rarest thing on Earth is considered to be Astatine, a naturally occurring element. Discovered in 1940, it's extremely scarce, with less than 1 gram existing in Earth's crust at any given time. Its rarity is due to its short half-life, causing it to decay rapidly. Due to this, Astatine has minimal practical applications and is primarily of interest in scientific research.
FAQs & Answers
- What is the half-life of Astatine? Astatine has a very short half-life, which contributes to its extreme rarity, making it difficult to study.
- Are there any practical uses for Astatine? Due to its rarity and instability, Astatine has minimal practical applications, primarily serving scientific research.
- How was Astatine discovered? Astatine was discovered in 1940 by chemists Emilio Segrè and Glenn T. Seaborg as part of their research on the transuranium elements.
- What makes Astatine rare? Astatine is rare because it is radioactive, has a short half-life, and less than 1 gram is naturally present in the Earth's crust at any time.
