Question: 1 / 2700

What type of bond is formed when electrons are shared between atoms?

Ionic bond

Covalent bond

A covalent bond is formed when electrons are shared between atoms. This type of bond occurs when two nonmetal atoms come close enough that their outer electron shells overlap, allowing them to share one or more pairs of electrons. This sharing creates a strong connection between the atoms, stabilizing them by achieving a complete valence shell, which is often the goal of atoms to reach a more stable energy state.

In covalent bonding, the number of shared electron pairs determines whether a single, double, or triple bond forms. As a general principle, the more electron pairs that are shared, the stronger the bond will be. This is crucial in many biological processes and the formation of various molecules, including water and organic compounds.

Understanding covalent bonds is key in fields such as chemistry and biology, where the structure and function of molecules significantly influence their properties and interactions.
