Draw Lewis structures for the following elements and the resulting ionic compounds. See the examples above for help. Either scan or take a digital picture of your drawings and upload it below. You may also use a Paint, PowerPoint, or similar program to create your drawings and either upload the completed file or upload a screenshot of your work. Li + F → LiF

Mg+ S → MgS

Al+ N → AlN
