Flipped 3: Elements & Compounds
- What is the difference between an element and a compound?
All matter is made from atoms. Atoms are very, very small. A molecule is formed when atoms join together by chemical bonds.
There are over a hundred different types of atom, called elements. The atoms of a particular element are identical to each other. They cannot be changed chemically into any different element. For example a piece of pure sulfur consists only of sulfur atoms. No chemical process can break it down into a different substance.
Compounds are substances that contain atoms of at least two elements chemically combined. For example: magnesium oxide consists of magnesium atoms and oxygen atoms chemically bonded together.
