6 Elements That Form Covalent Bonds

Quick Links :

Covalent bonds are a fundamental concept in chemistry, where two or more atoms share one or more pairs of electrons to form a molecule. This type of bonding is crucial for the formation of a wide variety of compounds, from simple molecules like water and methane to complex biomolecules like proteins and DNA. Understanding the elements that form covalent bonds is essential for grasping the principles of chemistry and the behavior of molecules.

At the heart of covalent bonding are the elements that have the ability to share electrons. These elements are typically nonmetals, which are located in the upper right corner of the periodic table.
