Compound
Definition
A compound is a substance that is composed of two or more different elements chemically bonded together.
- The elements of a compound are combined in specific ratio.
- It have unique properties distinct from the elements they are composed of.
- Compounds are represented with its chemical formula. Chemical formula indicates the elements present in the compound and the relative number of atoms or ions of each elements.
Here’s an explanation with examples:
- Water (H2O): One of the most common compounds, water is composed of two hydrogen atoms bonded to one oxygen atom.
- Sodium Chloride (NaCl): Commonly known as table salt, sodium chloride is composed of one sodium atom bonded to one chlorine atom
Types of Compounds
Compounds can be classified into two types:
Molecular Compounds: Atoms bind through covalent bonds. Examples include: Carbon dioxide (CO2) Methane (CH4)- Ionic Compound: Held together by ionic bonds. Example: Table salt (NaCl): Comprising one sodium atom and one chlorine atom.
