A step-by-step explanation of how to draw the BCl3 Lewis Dot Structure (Boron trichloride).
For the BCl3 structure use the periodic table to find the total number of valence electrons for the BCl3 molecule. Once we know how many valence electrons there are in BCl3 we can distribute them around the central atom with the goal of filling the outer shells of each atom.
Note, that as several viewers have pointed out, at 2:53 in the video I say "Bromine" instead of Boron. I meant to say "Boron".
Note that Boron can have a full outer shell with only six valence electrons. In the Lewis structure for BCl3 the central atom (Boron) will only have six valence electrons.
In the Lewis structure of BCl3 structure there are a total of 24 valence electrons. BCl3 is also called Boron trichloride.
---- Steps to Write Lewis Structure for compounds like BCl3 ----
1. Find the total valence electrons for the BCl3 molecule.
2. Put the least electronegative atom in the center. Note: Hydrogen (H) always goes outside.
3. Put two electrons between atoms to form a chemical bond.
4. Complete octets on outside atoms.
5. If central atom does not have an octet, move electrons from outer atoms to form double or triple bonds.

Lewis Structures, also called Electron Dot Structures, are important to learn because they help us understand how atoms and electrons are arranged in a molecule, such as Boron trichloride. This can help us determine the molecular geometry, how the molecule might react with other molecules, and some of the physical properties of the molecule (like boiling point and surface tension).
