The scientific chemical formula of sodium is Na.
Sodium is a chemical element with the atomic number 11 and is represented by the symbol ‘Na’ in the periodic table. The symbol comes from the Latin word ‘Natrium’, which refers to sodium carbonate. Sodium is an alkali metal, which means it is highly reactive and is found in Group 1 of the periodic table. In its natural state, sodium is never found in its elemental form due to its reactivity. Instead, it commonly occurs in nature as part of compounds, such as table salt (sodium chloride, NaCl).
