Symbol for sulfur:

**The reasoning** Chemical symbols are the universal "shorthand" used by scientists worldwide to represent elements. **Sulfur** is a non-metallic element, and its official symbol is simply **S** (capital S). This comes from the Latin name *Sulphur*. Chemical symbols follow strict rules set by IUPAC (International Union of Pure and Applied Chemistry): they're either **one capital letter** (like C for Carbon, O for Oxygen) or **one capital followed by one lowercase** (like Ca for Calcium, Cl for Chlorine). Sulfur uses just the single capital letter. **Why the wrong options tempt you** - **Su, Sl, Sf** look like they could be abbreviations of "Sulfur," especially if you're guessing based on the first two letters. But these aren't official symbols for any element. The trap here is assuming symbols always use two letters or directly abbreviate the English name—that's not how the system works. **Quick takeaway** Learn the common element symbols by heart (H, C, N, O, S, P, etc.)—they're your chemistry alphabet and will appear in every exam from WAEC to JAMB, no exceptions!
