There are three main characteristics of compounds. They consist of elements in a specific ratio that always remains the same. Compounds also have a chemical formula, like H₂O (water) or CO₂ (carbon dioxide). In addition, we can only separate the molecules chemically, not physically. Mixtures, on the other hand, are easy to separate physically.
Prepare yourself to take this "Elements compounds and mixtures quiz for grade 7th." We came to know the difference between a mixture, compound, and element in chemistry class. A compound is a substance made up of two or more elements, whereas an element is a substance that cannot be split into simpler substances.

In chemistry class, we learn about mixture, too. Mixture is a combination between two compound. Example of mixture is: Salt, sugar, etc. The main differences between the three is that the element cannot be reduced to any simpler form while the mixture can be separated using physical means and the compound is separated by use of chemical means.
