What is the chemical symbol for sodium?

The chemical symbol for sodium is "Na," which is derived from the Latin name "Natrium." Each chemical element has a unique one or two-letter symbol assigned to it, following the conventions of the periodic table. Sodium is an essential element in many biological processes and is commonly found in table salt (sodium chloride). Understanding chemical symbols is crucial for interpreting chemical reactions and formulas accurately, which is fundamental in fields like chemistry, biology, and various applications in the beauty and wellness industry as well. The other symbols listed do not correspond to sodium: "Sn" represents tin, "So" is not a recognized chemical element symbol, and "Sd" is also not valid within the periodic table. Thus, "Na" is the correct representation for sodium.
