Elements and Compounds - what's the difference?

This video tutorial explains the difference between elements and compounds. It begins by highlighting the importance of understanding these concepts and suggests reviewing previous videos on atoms and the periodic table.

Compounds are described as substances formed by the bonding of two or more different elements. Examples are provided to illustrate the differences, such as NaCl being a compound and Fe being an element.
