Covalent bonding (sharing)

Covalent bonding is where atoms share electrons.

To remember this, think of two people (non-metal) cooperating and covered by a veil (covalent) and deciding to share the rest of their lives together.

Covalent = cooperate = sharing
Covalent = sharing

Example

Within carbon dioxide molecules, a carbon atom shares all of the electrons in its outer shell with two oxygen atoms.
