Write the complete balanced equation for the decomposition of sodium chloride (nacl)

Decomposition equation of sodium chloride is given below: 2NaCl=>2Na+Cl2

Explanation:

A molecule of sodium chloride when subjected to decomposition it is decomposed into sodium and chlorine.The chemical equation can be written as:  NaCl=>Na+Cl2

The above mentioned equation is not a balanced chemical equation.In a balanced chemical equation the number of atoms of each element of reactants must be equal to number of atoms of each element of products.so to balance the above mentioned equation we shall write the required coefficient in reactants and products.In such a way the balanced equation will be 2NaCl=>2Na+Cl2

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
