Which chemical formula represents sulfur hexafluoride?

• A. SF4
• B. S6F
• C. S2F6
• D. SF6

Answer: (D)

Verified step by step guidance

1. Identify the prefix 'hex-' in the name 'sulfur hexafluoride,' which indicates the number 6 for fluorine atoms.
2. Recognize that 'sulfur' corresponds to the element symbol 'S' and 'fluoride' corresponds to fluorine with the symbol 'F'.
3. Combine the element symbols with the correct number of atoms: one sulfur atom (S) and six fluorine atoms (F6).
4. Write the chemical formula by placing the sulfur symbol first followed by the fluorine symbol with the subscript 6, resulting in SF6.
5. Confirm that the formula SF6 matches the name sulfur hexafluoride, distinguishing it from other options like SF4, S6F, or S2F6.
