It's freezing point is around 575.3°F! This number also applies to it's melting point. It's evaporation point is around 638.3°F. It is considered a metalloid. It's atomic mass is 210 U. It's density is around 8.91–8.95 g/cm³ (estimated) ]]> 2023-02-16 04:25:53 UTC https://padlet.com/kalmaraz27/zmymeomvmnmcjce6/wish/2484468767 kalmaraz27 https://padlet.com/kalmaraz27/zmymeomvmnmcjce6/wish/2485807724 Astatine is not flammable. Instead, it is reactive, but it is the least reactive, but still reactive.]]> 2023-02-17 02:19:04 UTC https://padlet.com/kalmaraz27/zmymeomvmnmcjce6/wish/2485807724 kalmaraz27 https://padlet.com/kalmaraz27/zmymeomvmnmcjce6/wish/2485942693 Astatine has no known biological role. It is toxic due to its radioactivity. Astatine can be obtained in a variety of ways, but not in weighable  amounts. So in a way, if it is ingested by a human. You could end up with an irritated nose, air passage and lungs. Therefore, it is not safe and is in fact a very highly radioactive element. ]]> 2023-02-17 05:01:57 UTC https://padlet.com/kalmaraz27/zmymeomvmnmcjce6/wish/2485942693 kalmaraz27 https://padlet.com/kalmaraz27/zmymeomvmnmcjce6/wish/2485951801 https://www.livescience.com/39514-facts-about-astatine.html

This could be because the half life of the most stable isotope is only 8 hours, and only tiny amounts have ever been produced. So it's basically useless and there's no price for it. ]]> 2023-02-17 05:22:31 UTC https://padlet.com/kalmaraz27/zmymeomvmnmcjce6/wish/2485953532 kalmaraz27 https://padlet.com/kalmaraz27/zmymeomvmnmcjce6/wish/2485964749 The number of protons that Astatine has is 85. This also applies to its electrons as well. The number of valence electrons that astatine has is around 7, they only require one additional electron to form a full octet. ]]> 2023-02-17 05:44:07 UTC https://padlet.com/kalmaraz27/zmymeomvmnmcjce6/wish/2485964749 kalmaraz27 https://padlet.com/kalmaraz27/zmymeomvmnmcjce6/wish/2485965822 2023-02-17 05:46:10 UTC https://padlet.com/kalmaraz27/zmymeomvmnmcjce6/wish/2485965822 kalmaraz27 https://padlet.com/kalmaraz27/zmymeomvmnmcjce6/wish/2485969149 Astatine's atomic number is 85. The group it's in for the periodic table is the Halogen Elements. The period for Astatine is 6. It's symbol is At.  Because astatine has no stable or long-lived isotopes, it was given its name from the Greek word astatos, meaning "unstable."]]> 2023-02-17 05:51:46 UTC https://padlet.com/kalmaraz27/zmymeomvmnmcjce6/wish/2485969149 kalmaraz27 https://padlet.com/kalmaraz27/zmymeomvmnmcjce6/wish/2485975755 2023-02-17 06:04:45 UTC https://padlet.com/kalmaraz27/zmymeomvmnmcjce6/wish/2485975755 kalmaraz27 https://padlet.com/kalmaraz27/zmymeomvmnmcjce6/wish/2485977155 2023-02-17 06:07:14 UTC https://padlet.com/kalmaraz27/zmymeomvmnmcjce6/wish/2485977155 kalmaraz27 https://padlet.com/kalmaraz27/zmymeomvmnmcjce6/wish/2485977968 Astatine is a chemical element with the symbol At and atomic number 85. It is the rarest naturally occurring element in the Earth's crust, occurring only as the decay product of various heavier elements. It can be obtained naturally from thorium or uranium decay. It doesn't have a lot of abundance here on Earth because there is approximately 25 grams of astatine on Earth at any given time
