Often asked: What Is The Definition Of Compound In Science?

What is definition of compound?

A compound is a material formed by chemically bonding two or more chemical elements. The type of bond keeping elements in a compound together may vary: covalent bonds and ionic bonds are two common types.

What is the best definition of a compound?

A compound is a substance formed when two or more chemical elements are chemically bonded together. Example 1: Pure water is a compound made from two elements – hydrogen and oxygen. The ratio of hydrogen to oxygen in water is always 2:1. Each molecule of water contains two hydrogen atoms bonded to a single oxygen atom.
