Now let's consider something that is more directly observable. Let's look at the chemical reactivity of some of the elements and relate that reactivity to some of the properties we have just talked about.
Reactivity means just what it says.
A highly reactive element reacts very easily, maybe even violently, with lots of other elements or compounds. In your lab work for this lesson, you will make observations comparing the reactivities of some of the elements by observing the reactions of a few. The pages in this section pertain directly to your lab work for this lesson. If your schedule permits, it would be best to do this portion of the lesson after doing the lab work.
