Which element has the symbol O?

Which element has the symbol O?

• A. Oxygen
• B. Neon
• C. Carbon
• D. Fluorine

Answer: (A)

Oxygen is the element whose chemical symbol is O. In chemistry, each element has a unique symbol, often derived from its name, and Oxygen’s symbol uses the initial letter of its name. This symbol is used in formulas and reactions to stand for the element. Oxygen is a nonmetal and makes up about 21% of Earth's atmosphere; it commonly exists as diatomic molecules, O2, which we breathe. The other options correspond to different symbols: Neon is Ne, Carbon is C, and Fluorine is F. So the symbol O belongs to Oxygen.
