Which of the following molecules is diatomic in nature?

Correct option is B

The correct answer is: (b) Oxygen

Explanation:

• Oxygen (O₂) is a diatomic molecule, meaning it consists of two atoms bonded together.

• In nature, elemental oxygen exists as O₂ because this configuration is more stable than single oxygen atoms.

• Diatomic molecules include gases like O₂, N₂, H₂, Cl₂, etc.

Information Booster:

• Diatomic gases = molecules made of two atoms (same or different elements).

• Common elemental diatomic molecules: H₂, N₂, O₂, F₂, Cl₂, Br₂, I₂.

• O₂ is essential for respiration and combustion.

• Diatomic molecules are generally more stable than monoatomic forms.

• O₂ has a double covalent bond between atoms.

• Exists as a paramagnetic gas due to unpaired electrons.

Additional Information:

• Helium – A noble gas, monoatomic in nature (exists as single atoms).

• Argon – Another noble gas, also monoatomic.

• Phosphorus – Exists as P₄ (tetra-atomic molecule) in its elemental form, not diatomic.
