Interpretation: Balanced chemical equation of an alkali metal with chlorine.
Concept introduction: Alkali metals belong to group
Alkali metals are very reactive and form compounds with chlorides, oxides and water. Alkali metals combine with non-metals and there is a transfer of electrons from metals to non-metals and thus ions are formed where metals have a positive charge and non-metals are negatively charged. Thus, alkali metals generally form ionic compounds and react vigorously to produce compounds with non-metals.
The reaction of alkali metals with non-metals produces energy which is released in the form of heat or light. Such reactions, in which energy is released in the form of heat and light are referred to as exothermic reactions. The reaction in which energy is absorbed from the surroundings are known as endothermic reactions.
In general, combination reaction is always exothermic in nature. Thus, exothermic reaction gives off energy and endothermic reactions absorb energy.
In order to have a balanced chemical equation, the atoms on both the product and reactant side of a combination reaction should be same. Thus, the
