How did silicon get its atomic symbol?

Answer 1

they use that symbol because back then, a lot of scientists were Italian, therefore they gave the chemical the Italian name instead of the English. In this case the symbol for silicon is Si because si are the first two letters of the chemical.

Answer 2

The atomic symbol for an element is typically derived from its name. In the case of silicon, its symbol "Si" comes from its Latin name "silicium." The symbol "Si" was established by chemist Jöns Jacob Berzelius in the early 19th century.
