A covalent bond forms between two atoms or radicals, because each needs one or more extra electrons in order to form a more stable electron configuration, but neither has a strong enough electronegativity to pull an electron away from the other one, so therefore they just share electrons.

A covalent bond forms when atoms share electrons in order to achieve a more stable electron configuration. This sharing of electrons allows both atoms to fill their outer electron shells and decrease their overall energy.
When atoms share electrons, they form a chemical bond, or covalent bond.
No, nitrogen (N) and fluorine (F) are both nonmetals, and they typically form a covalent bond when they combine. A covalent bond involves the sharing of electrons between the two atoms.
Hydrogen can form a covalent bond with nitrogen to create ammonia (NH3).
No, oxygen and nitrogen do not form an ionic bond. They are both nonmetals and tend to form covalent bonds where they share electrons rather than transfer them.
The element that can form diatomic molecules joined by a single covalent bond is hydrogen (H2). Each hydrogen atom shares one electron to form a single covalent bond between them.
