Diatomic Molecules: Definition, Explanation And Examples

Diatomic molecules are molecules with two atoms in their structure. This could be two atoms attached to one nucleus or two atoms attached to more than one nucleus (heteronuclear).

The world of the very minuscule dictates the characteristics that the world of the very big exhibits. This “world of the small” is inhabited by atomic and sub-atomic particles.

Atoms can be thought of like Lego blocks; they combine together in different ways to make different things. So, the same Lego blocks can make a boat or a bridge, as the atoms that can make a blade of grass or a giraffe.

When two or more atoms come together, they form a molecule. The number of atoms in a molecule denotes the prefix, so a molecule containing two atoms is called diatomic.

There are different types of diatomic molecules. Let’s begin this discussion by better understanding the workings of a molecule.
