Element symbols are based on the Latin names for the elements.

For example, "Sodium" and "Sulfur" both start with 'S,' so their symbols are Na and S, respectively.
The symbols of elements are derived from their names in various ways, often using the first letter or first two letters of the element's name, in a standardized manner based on the element's English or Latin name. For example, the symbol for sodium is Na, derived from the Latin name "natrium." You can find the symbols of elements on the periodic table of elements.
