* Chemical Bonding: Compounds are formed when two or more different elements chemically combine in a fixed ratio. This involves the sharing or transfer of electrons, creating a new structure and arrangement of atoms.
* New Properties: This new arrangement and bonding leads to entirely different physical and chemical properties compared to the original elements.
* Example: Sodium (a highly reactive metal) and chlorine (a poisonous gas) combine to form sodium chloride (table salt), a white, crystalline compound that's essential for life.
* Unique Identity: The resulting compound has its own unique identity and properties, distinct from its constituent elements.
Here are some key characteristics of a compound:
* Fixed Composition: The elements in a compound always combine in a specific ratio.
* Distinct Properties: The compound exhibits properties that are different from the elements that make it up.
* Chemical Change: The formation of a compound is a chemical change, meaning the original elements are transformed into something entirely new.
