Can you combine two atoms? Yes they are very tiny, but you can mix two substances together to form molecules and compounds. What are they? Get your toothpicks and gumdrops or marshmallows to find out!
In the previous Related Lesson, found in the right-hand sidebar, you learned about elements.
Let's find out!
Before you begin learning new information, let's review what you learned in the previous Related Lessons.
Look at the following information from the periodic table of elements:
It is possible to combine two or more elements. When this happens, the result is called a molecule.
Sometimes, when elements are combined, it creates a compound. A compound is created when two or more different elements are combined. Therefore, a compound is also a molecule, but a molecule is not always a compound.
For example, O2 is only a molecule because it combines the same element. CO2 is both a compound and a molecule because it combines different elements.
To learn more about elements and compounds, watch Element vs Compound from MooMooMath and Science:
Then, read Compound Basics, from Chem4Kids.com Molecules from Ducksters.
Think about your ideas, then continue on to the Got It? section for some practice.
