When sodium (Na) reacts with chlorine (Cl2), the atoms rearrange to form a new substance, sodium chloride (NaCl), also known as table salt.
The chemical reaction between sodium and chlorine can be represented as follows:
2Na + Cl2 → 2NaCl
In this reaction, sodium atoms lose one electron each, while chlorine atoms gain one electron each, resulting in the formation of positively charged sodium ions (Na+) and negatively charged chloride ions (Cl-). These ions then combine to form an ionic compound, sodium chloride (NaCl).
This process involves a chemical change, as the starting materials (sodium and chlorine) are transformed into a new substance with different properties (sodium chloride).
Therefore, the combination of sodium and chlorine to produce chloride is indeed a chemical reaction.
