* Bonding pairs are pairs of electrons shared between two atoms to form a covalent bond.
* Electrons are fundamental particles that carry a negative charge.
Think of it this way:
* A single bond involves one bonding pair (two electrons).
* A double bond involves two bonding pairs (four electrons).
* A triple bond involves three bonding pairs (six electrons).
Example:
* Water (H₂O) has two bonding pairs (one for each H-O bond) but a total of 10 electrons.
* Carbon dioxide (CO₂) has two double bonds, meaning four bonding pairs and a total of 16 electrons.
In summary:
* The number of bonding pairs tells you how many bonds are present in a molecule.
* The total number of electrons in a molecule is determined by the number of protons in the atoms that make up the molecule.
