How many atoms are present in nitrogen gas (N2)?

• A. One
• B. Two
• C. Three
• D. Four

Answer: (B)

Nitrogen gas is composed of molecular nitrogen, which has the chemical formula N2. This notation indicates that each molecule of nitrogen gas consists of two nitrogen atoms bonded together. In this diatomic form, N2 molecules are the most common and stable form of nitrogen found in nature. Thus, when discussing the number of atoms in a single molecule of nitrogen gas, it clearly contains two atoms of nitrogen. This understanding is crucial in various scientific contexts, especially when examining molecular structure, chemical reactions, or gas laws.
