What role does sodium metal play in the chemical reaction with chlorine gas?

Sodium metal acts as a reactant in the chemical reaction with chlorine gas. In this reaction, sodium donates an electron to chlorine, leading to the formation of sodium chloride (table salt). Sodium, an alkali metal, is highly reactive and readily combines with halogens like chlorine to form ionic compounds. The electron transfer during the reaction results in the creation of positively charged sodium ions and negatively charged chloride ions, which then bond together due to electrostatic attraction. This process demonstrates sodium's role as a fundamental building block in the formation of new substances when it reacts with other elements.
