Hello, This is a Storyboard That on Elements, Compounds, and Molecules.
An element is a substance that can not be broken down into anything else.
Some examples of elements are oxygen, carbon, sulfur, nitrogen, uranium, and plutonium.
A compound is formed by two or more elements when they react.
Some examples of compunds are Carbon Dioxide (CO2), Water (H20), Carbon Monoxide (CO), and Ammonia (NH3).
A molecule is a group of atoms that are linked together, and usually make a compound, but sometimes can make an element. Some examples are Sulfur (S8), Ammonia (NH3), and Oxygen (O2).
In Conclusion: - Molecules are groups of atoms linked together by chemical bonds. - Elements are substances that connot be broken down any further - Compounds are substances made of 2 or more elements. Compounds are usually molecules.
