What are Compounds?
Before we dive into the examples, let’s define what compounds are. A compound is a substance formed when two or more different elements are chemically bonded together. This bonding can occur through various means, such as sharing electrons or exchanging electrons. Compounds can be found naturally or synthesized in a laboratory.
Types of Compounds
There are several types of compounds, including:
Molecular Compounds
Molecular compounds are formed when two or more non-metal atoms share electrons to form a covalent bond. Examples of molecular compounds include water (H2O), carbon dioxide (CO2), and methane (CH4).
Ionic Compounds
Ionic compounds are formed when a metal atom loses one or more electrons to form a positive ion, while a non-metal atom gains one or more electrons to form a negative ion. The electrostatic attraction between the oppositely charged ions holds them together. Examples of ionic compounds include sodium chloride (NaCl), calcium carbonate (CaCO3), and ammonium nitrate (NH4NO3).
Organic Compounds
Organic compounds are carbon-based compounds that contain hydrogen and other elements such as oxygen, nitrogen, and sulfur. Examples of organic compounds include sugars, fats, and proteins.
