In general, there are two approaches you can use to determine the number of lone pairs. The first one, which is also what you should eventually aim for, is to learn the common bonding patterns of the elements in the second row and recognize the number of lone pairs and formal charges based on those.
This chemistry video tutorial provides a basic introduction into drawing lewis dot structures and provides an explanation on how to calculate the number of lone pairs using a formula /...
The quotient gives the value of the number of sigma bond pairs and the remainder divided by 2 gives the number of lone pairs. Explanation: The number of valance electrons counted divided by 8 will give the number of sigma bonds formed.
The Lewis structure indicates that each Cl atom has three pairs of electrons that are not used in bonding (called lone pairs) and one shared pair of electrons (written between the atoms). A dash (or line) is usually used to indicate a shared pair of electrons:
In this video I go step by step through how you can work out the number of lone pairs and the number of bonding pairs around the central atom in a molecule.
To identify the orbitals of the lone pair electrons in non-aromatic compounds, we can follow a two-step approach. Step 1: Add any missing lone pair electrons to the heteroatoms (atoms other than carbon and hydrogen). Step 2: Determine the hybridization of any atoms with lone pairs (heteroatoms). Lone pairs occupy the hybridized orbitals.
