What is this lesson about?

This lesson is mostly about how different elements interact to form different compounds. You will also learn how to represent different elements together in one compound and some of the measurements you can take with those compounds.

Why is it critical to understand?

If you are not able to understand how different elements come together and how those elements and compounds are recognized, then you will not be able to continue with lessons like nomenclature, valene electron dot structures (Lewis structures), and chemical equations. Beyond that, knowing how elements are put together also allows you to know how to take them apart. Whether you can dissolve them in water or whether you need to burn them in a fire. The type of the bonding that occurs also give you clues on how strong that bond is and therefore, what that material you have created can be used for.
