In this video we'll go through the steps to write the CN- Lewis Dot Structure (Cyanide ion).

For the CN- structure use the periodic table to find the total number of valence electrons for the CN- molecule. Once we know how many valence electrons there are in CN- we can distribute them around the central atom with the goal of filling the outer shells of each atom.

In the Lewis structure of CN- structure there are a total of 10 valence electrons. CN- is also called Cyanide ion.

----- Steps to Write Lewis Structure for compounds like CN- -----
1. Find the total valence electrons for the CN- 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 Cyanide ion. 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).
