Worksheet Overview

The alphabet contains 26 letters, but how many words can you think of... thousands, hundreds of thousands, millions? Combining the letters of the alphabet allows us to create lots and lots of words.


This is similar to chemistry. The Periodic Table is composed of over a hundred elements, 118 in fact, and when these elements combine they form compounds. This means that there are billions of possible compounds in existence.
