The bond formed when atoms share electrons is called a covalent bond.

Here's why:

* Covalent means "sharing together."

* In a covalent bond, two atoms share one or more pairs of electrons to achieve a stable electron configuration (like the noble gases).

* This sharing creates a strong attraction between the atoms, holding them together in a molecule.

There are different types of covalent bonds, including:

* Single covalent bond: Two atoms share one pair of electrons.

* Double covalent bond: Two atoms share two pairs of electrons.

* Triple covalent bond: Two atoms share three pairs of electrons.

Examples of molecules formed by covalent bonds:

* Water (H₂O)

* Carbon dioxide (CO₂)

* Methane (CH₄)

* Oxygen (O₂)
