Chemical Compound
A Chemical Compound (pronunciation: /ˈkɛmɪkəl ˈkɒmpaʊnd/) is a substance formed when two or more chemical elements are chemically bonded together.
Etymology
The term "Chemical Compound" originates from the Latin word "componere", which means "to put together". The term was first used in the 17th century to describe the process of combining various elements to form a new substance.
Definition
In chemistry, a Chemical Compound can be defined as a distinct substance that is produced by a chemical reaction and contains two or more atoms bonded together. These atoms can be of the same element, such as in Oxygen (O2) or different elements, such as in Water (H2O).
Types of Chemical Compounds
Chemical Compounds can be broadly classified into two types: molecular compounds and ionic compounds.
- Molecular Compounds: These are compounds where the elements share electrons via covalent bonds. Examples include Carbon Dioxide (CO2) and Methane (CH4).
- Ionic Compounds: These are compounds formed by the transfer of electrons from one atom to another, resulting in the formation of ions. Examples include Sodium Chloride (NaCl) and Magnesium Oxide (MgO).
