What is the key difference between an element and a compound? | An element is one basic unit while a compound is two or more elements chemicaly bonded. |
What are two differences between a compound and a mixture. | A compound's components are chemically bound together while a mixture's are physically combined. A compound can only be separated with chemical change, but a mixture can be separated by physical means. |
