Which symbol represents the element Silicon?

• A. Si
• B. Sn
• C. C
• D. V

Answer: (A)

Chem symbols are the short abbreviations used for elements in formulas. Silicon’s symbol is Si, with S capital and i lowercase, reflecting the standard rule of capitalization: one or two letters, first letter uppercase and second if present lowercase. This two-letter form comes from the element’s name and is used consistently in chemistry to identify silicon in compounds and discussions, including in electronics where silicon dominates. Other common symbols correspond to different elements: Sn stands for tin, C for carbon, and V for vanadium. They don’t represent silicon, which is why Si is the correct symbol. Silicon is known for its role in semiconductors and has atomic number 14.
