a pure substance that can be separated into different elements by chemical means

Reason: Sodium chloride is a chemical compound (not a mixture). Its constituent elements (Na and Cl) are chemically bonded and can only be separated by chemical processes (e.g., electrolysis/reduction), not by physical separation.
