Question

Cs reacts with chlorine to form?

Answer 1

Symbol ‘Cs’ stand for the element ‘Caesium ‘, ‘Cs’ lies in the group one of the periodic table. and the halogen atom ‘Chlorine’ stands for the symbol ‘Cl’ lies in the group seventeenth of the periodic table. Halogen reacts with alkali metals very readily.

Complete answer:
Alkali metals react with the halogen atoms very readily to form ionic halides.
Let’s now see the case given to us in the question. For doing so, let’s have a brief detail about the given halogen atom and the alkali metal.
So our given alkali metal is ‘Caesium ‘. it lies in the group $1$ and the period $6$ of the periodic table and falls in the category of alkali earth metals.
Our given halogen atom is ‘Chlorine’ , it lies in the period $3$ and the group $17$ of the periodic table.
alkali metals react with the halogen atoms very readily to form ionic halides. Caesium metal forms Caesium halide as it reacts with chlorine atoms.
Now have a look at the reaction between the chlorine and the caesium metal.
$2Cs + C{l_2} \to 2CsCl$
So, when Caesium reacts with chlorine, it forms caesium chloride.
So from the above discussion, the reaction between the Caesium metal and the halogen chlorine is crystal clear.

Note:
Caesium is a very important metal in the industrial field. Drilling fluids based on Caesium formate are used widely in the oil industries. Caesium is also an important component for the fuels of thermionic generators, that converts heat into the form of electricity.
