Questions using triple bond
Problem 1
A nitrogen molecule (N₂) contains a triple bond. How many electrons are shared between the two nitrogen atoms?
Answer and explanation
6
A triple bond is 3 shared pairs, and 3 pairs × 2 electrons = 6 electrons.
Problem 2
How many shared electrons are represented by a triple bond? Show the reasoning, not just the conclusion.
Hints
A shared pair is not ownership transferred permanently to only one atom.
Answer and explanation
Six electrons in three shared pairs in the simple bond model.
Problem 3
A molecule of N₂ has a triple bond. How many shared (bonding) electrons are between the two atoms?
Answer and explanation
6
A triple bond is 3 shared pairs, and 3 × 2 = 6 electrons.
