What type of bond is formed when two atoms share a pair of electrons?

When two atoms share a pair of electrons, a covalent bond is formed. In this context, the correct answer is a nonpolar covalent bond, which specifically refers to a bond that occurs between two identical atoms or atoms with similar electronegativity, resulting in an equal sharing of the electrons. This type of bond does not create a dipole because the electron density is evenly distributed between the two atoms.

In a polar covalent bond, however, the atoms involved have different electronegativities, causing the electrons to be shared unequally. This results in a partial positive charge on one atom and a partial negative charge on the other. Therefore, while polar covalent bonds also involve the sharing of electrons, they differ in how evenly those electrons are shared.

A hydrogen bond is an attraction between a hydrogen atom covalently bonded to an electronegative atom and another electronegative atom, not a bond formed through sharing electrons between two atoms directly. Lastly, the term ionizing bond is not standard in chemistry; instead, ionic bonds are formed when electrons are transferred from one atom to another, leading to the creation of charged ions that attract each other.

Understanding the distinctions between these bond types clarifies why the formation of a non
