Question

What will be the product(s) of the following reaction: $Cs + B{r_2} \rightleftharpoons ?$

Answer 1

Alkali earth metals are the metals that can easily undergo loss of electrons. halogens are the chemical elements that are mostly non-metals. Metals and non-metals react with each other and form a compound known as salt. Caesium is a metal that reacts with bromine which is a non-metal to form caesium bromide.

Complete Step By Step Answer:
Periodic table is the representation of chemical elements that are arranged in the increasing order of atomic numbers. These elements were arranged in vertical columns and horizontal rows. The vertical columns were known as groups and the horizontal rows were known as periods.
Alkali earth metals are the chemical elements that belong to group $1$ . Halogens are the chemical elements that belong to group $17$ .
Metals in alkali earth metals react with non-metals in halogens to form salt. Halogens are known as salt-formers.
Caesium is the most electropositive element in the periodic table as it can easily undergo oxidation which means loss of electrons. Bromine belongs to halogen, which is a non-metal.
Caesium and bromine react with each other to form an ionic compound known as caesium bromide.
The balanced chemical equation is: $2Cs + B{r_2} \rightleftharpoons 2CsBr$ .

Note:
Ionic compounds were formed by the atoms that have the difference in electronegativity. Caesium is the most electropositive element with low electronegativity and bromine is a non-metal with high electronegativity. Both these elements combine to form an ionic compound. But this compound is not stable as it easily decomposes to caesium oxide on heating.
