The only way to make it is with a particle accelerator, the amounts made are too small to see, and a given sample decays almost completely in a few days.
Astatine is rarely encountered in nature, but when it does occur, it is typically in very small amounts and with a short half-life. Given its extremely limited presence and reactivity, there is insufficient information to definitively conclude whether astatine is odorless or not.
Helium, the noble gas with the smallest atoms.
The atomic number of astatine (At) is 85.The atomic weight of At is 210 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!
Astatine is an element with the symbol At.
Astatine is not typically found in uranium ore. It is a rare and radioactive element that is mainly produced in laboratories by bombarding bismuth targets with alpha particles. Natural occurrences of astatine are extremely rare and limited to trace amounts in uranium ores or as decay products of heavier elements.
Astatine has 125 neutrons
Francium and astatine are both highly reactive elements located in the same period of the periodic table. When combined, they are expected to form a salt molecule due to their reactivity. No specific compound formula can be determined without further information.
Some common compounds formed by astatine include hydrogen astatide (HAt), astatine monochloride (AtCl), astatine monobromide (AtBr), and astatine monoxide (At2O). Due to the scarcity and radioactive nature of astatine, its compounds are not commonly studied.
The color of the element astatine is unknown.
The Latin language name of astatine is astatium.
Astatine has 85 protons.
The chemical symbol of astatine is At
