How many atoms are there in a nitrogen molecule?
Think it through first, then pick an option.
- a 1
- b 2
- c 3
- d 4
Answer and explanation
Correct answer: b 2
The nitrogen molecule is N₂: two atoms.
Why the other options are wrong
- a 1: Metals and inert gases are written as single atoms; nitrogen's molecule is N₂.
- c 3: The three-atom molecule is ozone, O₃; nitrogen is N₂.
- d 4: Phosphorus, P₄, has four atoms; nitrogen is N₂.
