0 ratings Report this course

This video tutorial (about 15 minutes) covers the formation of ions and writing ionic formulae. You'll learn what an ion is, why and how they form, as well as two methods to figure out ionic formulae.

You'll also get a worksheet to let you practice writing ionic formulae using both methods covered in the tutorial. To help with this a table of the common ions used in junior high school science is also included. A separate document has the worked answers to the practice worksheet so you can check them and figure out why you got any questions wrong.
