What are compounds formed from?

Compounds are formed from atoms that undergo a chemical reaction. This process involves the combination or rearrangement of atoms to create new substances with different properties than the original elements. During chemical reactions, atoms bond together in specific ways, resulting in the formation of molecules that constitute a compound.

For instance, when hydrogen and oxygen atoms react chemically, they form water, which is a compound made up of these two elements. The formation of compounds is fundamental in chemistry and biology, as it relates to how elements interact and combine to create the diverse array of substances found in nature. Understanding this process is crucial for studying chemical and biochemical phenomena, as well as the basic structure of matter itself.
