What is the reaction between potassium astatine with bromine?

When potassium astatine reacts with bromine, it forms potassium bromide and astatine. The reaction is likely to be quite vigorous due to the high reactivity of astatine and the relative electronegativity difference between the two elements.


Which is more reactive At or Br?

Fluorine (F) is more reactive than both Astatine (At) and Bromine (Br) due to its higher electronegativity and smaller atomic size. Astatine is more reactive than bromine due to its lower electronegativity and larger atomic size.


What element has the strongest attraction for electrons in a bond bromine astatine hydrogen lithium?

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.


Is astatine soluble in water?

Yes, astatine is slightly soluble in water, but the solubility is very low. Astatine forms astatide ions (At-) in water due to its high electronegativity and can react with water molecules to form various compounds, which limits its solubility.


Which is most electronegative metal?

Fluorine is the most electronegative element and not a metal. Among metals, the most electronegative is cesium.


What type of element is astatine?

What at the common compounds formed by astatine?

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.


What is astatine?

The color of the element astatine is unknown.


What can you say about reactivity of the halogens as you go down the group from fluorine to astatine?

Reactivity decreases. In other words, fluorine is the most reactive of the halogens while astatine is the lease reactive. This is because the ability to attract electrons(electronegativity) decreases as you go down the group.
