A bond is formed when electrons are shared between atoms.
<h3>What is the number of unshared pairs?</h3>
A bond is formed when electrons are shared between atoms. This is what we call a shared pair. A lone pair or unshared pair is one that is domiciled on only one of the atoms in the bond.
Let us now look at the molecule shown in image 1;
- The number of unshared pairs in atom a is 0
- The number of unshared pairs in atom b is 2
- The number of unshared pairs in atom c is 0
Let us now look at the molecule shown in image 2;
- The number of unshared pairs in atom a is 1
- The number of unshared pairs in atom b is 2
- The number of unshared pairs in atom c is 3
