Here's a breakdown:

* Electrons: Tiny particles that orbit the nucleus of an atom.

* Stabilizing: Atoms are most stable when they have a full outer shell of electrons (usually 8).

* Sharing: Atoms can share electrons with each other to achieve this stable configuration.

* Covalent bond: The shared electrons form a strong attraction between the two atoms, holding them together in a molecule.

Think of it like this: Imagine two people each holding one half of a sandwich. They share the sandwich, giving each other access to the whole thing. In a covalent bond, the two atoms share the electrons, giving each other a full outer shell and a more stable configuration.
