Flammability of gold element
WebFeb 23, 2024 · Gold is a very unreactive metal and is not flammable. In fact, gold is so unreactive that it is sometimes used as a coating to protect other, more reactive metals … WebAstatine is a dangerously radioactive element. Uses There are currently no uses for astatine outside of research. The half-life of the most stable isotope is only 8 hours, and only tiny amounts have ever been produced. A mass spectrometer has been used to confirm that astatine behaves chemically like other halogens, particularly iodine.
