How to Draw the Lewis Dot Structure for SrF2: Strontium fluoride

A step-by-step explanation of how to draw the SrF2 Lewis Dot Structure. For SrF2 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:    • Finding the Ionic Charge for Elements on t...  ). 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 SrF2. Note that SrF2 is also called Strontium fluoride.

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 SrF2 we think of it together with other SrF2 formula units in a crystal (NaCl is a good example of this: https://en.wikipedia.org/wiki/Sodium_....
