Description from the creator

A step-by-step explanation of how to draw the KF Lewis Dot Structure.

For KF we have an ionic compound and we need to take that into account when we draw the Lewis Structure. We’ll first draw the metal and put it in brackets with its charge on the outside (video: finding ionic charge: youtu.be/M22YQ1hHhEY).

Next, we'll draw the Lewis Structure for the F- ion and add brackets. We put the two ions together to complete the Lewis structure for KF. Note that KF is also called Potassium fluoride.

Note that is it more common to draw Lewis Structures for covalent (molecular) compounds where valance electrons are shared. In the case of ionic compounds, where we have a metal bonded to a non-metal (or group of non-metals), the Lewis diagram represents a formula unit. Many of these formula units make up a crystal lattice. So when we talk about the structure for KF we think of it together with other KF formula units in a crystal (NaCl is a good example of this: en.wikipedia.org/wiki/Sodium_chloride).
