2. Elements are substances that you can not break down into a smaller substance. Elements are made up of one type of atom. Elements make up compounds. Wait, what are compounds? By Timothy Bell

3. Compounds are two or more elements combined together. Compounds are made of elements such as oxygen, carbon, and hydrogen. One of our basic needs like water is a compound if you didn’t know.

4. Organic compounds are the important compounds of carbon. Because carbon atoms link to each other with ease, the basics of most organic compounds are carbon chains that vary in size. Hydrogen, nitrogen, and oxygen atoms are the most common atoms to be attached to carbon atoms.

5. Inorganic compounds are compounds that are lacking carbon or when carbon atoms are present they are linking to other atoms that are not carbon. One very common inorganic compound is water. Some inorganic compounds that contain carbon are carbonates.

6. Some types of organic compounds are methane which is CH4, ethane isC2H6, propane which isC3H8, ethene which is C2H4, etc.

7. Some types of organic compounds are carbohydrates which is CH2, lipids which are CH3, proteins have many different formulas but one example is C2H5NO2, etc.
