Which element has the atomic symbol "O"?

Which element has the atomic symbol "O"?

• A. Osmium
• B. Oxygen
• C. Gold
• D. Carbon

Answer: (B)

The element with the atomic symbol "O" is Oxygen. In the periodic table, each element is represented by a unique one- or two-letter symbol, and Oxygen is designated by the letter "O." This is a fundamental aspect of chemistry and helps in identifying elements quickly, especially when chemical formulas and reactions are written. Oxygen is a vital element for life on Earth, comprising about 21% of the Earth's atmosphere and playing a critical role in respiration for many organisms, as well as in combustion and various chemical processes. It is commonly found in water (H2O) and organic compounds, highlighting its importance in both biological and environmental science contexts. The other choices represent different elements with distinct symbols: Osmium has the symbol "Os," Gold is represented by "Au," and Carbon is denoted as "C." Each of these has unique properties and roles in various scientific fields, but they do not share the atomic symbol "O."
