Which one of the following is larger in size than the oxygen atom?
Correct answer: C. Carbon
- A. Fluorine
- B. Nitrogen
- C. Carbon
- D. Hydrogen
Explanation
Atomic size generally decreases across a period from left to right due to increasing nuclear charge. Oxygen is to the right of carbon in the periodic table, so it is smaller. Therefore, carbon, being to the left of oxygen, is larger in size.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
