The hydrogen astatide - HAt.
Astatine is a compound made from two or more different elements. Hope this helps! :D
There are more than three such elements: at least hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine, probably also astatine.
Examples of elements are... Hydrogen, Helium, Oxygen, Sodium, Bromine, Astatine, Bismuth and Mercury.
The chemical formula of hydrogen astatide is HAt.
Astatine can react with hydrogen to form hydrogen astatide (HAt) through a simple displacement reaction. This reaction is similar to the halogens' reactions with hydrogen when hydrogen halides are formed. Hydrogen astatide is a strong acid and highly reactive due to the polar covalent bond between hydrogen and astatine.
Hydrogen monoxide is made of two elements, hydrogen and oxygen.
Astatine typically forms bonds with elements like hydrogen, alkali metals (e.g., sodium, potassium), and metals in Group 2 (e.g., calcium, strontium) to achieve stability. It can also form bonds with halogens like chlorine and metals in higher oxidation states.
No slogans for chemical elements !
Astatine has the strongest attraction for electrons in a bond. Electronegativity generally increases as you move up and to the right on the periodic table, with astatine being at the top right corner among the elements mentioned.
Polyethylene is made from the elements Carbon and Hydrogen only.
Some radioactive elements in the periodic table are radium, uranium, plutonium, thorium, polonium, radon, francium, astatine, radium, and curium.
Astatine wouldn't form salt as readily as other elements in Group 17. Astatine is a radioactive metalloid. Other elements in Group 17 are nonmetals.
