Covalent bond

What is a Covalent Bond?

A covalent bond is a special way that tiny parts of things called atoms stick together. They share tiny particles called electrons. When atoms share electrons, they become happier and more balanced.

One easy example is a molecule of hydrogen, called H₂. The two hydrogen atoms share their electrons to stay together. This sharing works best when the atoms are fair and want the electrons the same.

Where Did the Idea Come From?

The idea of covalent bonding started with a scientist named Gilbert N. Lewis in 1916. He showed how atoms can share pairs of electrons to stay connected. Later, other scientists like Irving Langmuir helped explain more about it.

Why Do We Know About It?

Covalent bonds are very common in the world around us. They help make many things we use every day, like plastics and even some foods. These bonds help atoms form molecules, which are groups of atoms stuck together. This makes the world full of different substances with special properties.
