In addition to the site provided by Ms. Sue the following information may help.

Oxygen is an element and hydrogen is an element. If you combine oxygen with hydrogen the compound, water, is produced. Water, the compound, has different properties than either hydrogen or oxygen.

A compound is different from an element in that it is made up of two or more different elements bonded together. An element, on the other hand, consists of only one type of atom.

To understand this difference, you can look at the periodic table of elements. Elements are represented by different symbols (such as H for hydrogen, O for oxygen, and C for carbon) and have distinct atomic numbers. Elements cannot be chemically broken down into simpler substances.

Compounds, on the other hand, are formed when atoms of different elements chemically combine together. For example, water (H2O) is a compound made up of two hydrogen atoms and one oxygen atom bonded together. Compounds have different properties than their constituent elements and can be broken down into their component elements through chemical reactions.

In summary, while elements are simple substances made up of one type of atom, compounds are formed when two or more different elements combine chemically.
