A chemical bond formed when two atoms share two pairs of electrons is a ________ bond;it is best described as ________.

Question

Quizplus · Accepted Answer

A double bond is formed when two atoms share two pairs of electrons. This type of bond is always a covalent bond as it involves the sharing of electrons between atoms. In contrast, an ionic bond is formed when one atom completely transfers electrons to another atom resulting in the formation of ions with opposite charges that are attracted to each other. Therefore, choices B, D, and E are incorrect because they suggest the formation of an ionic bond, which cannot occur when sharing two pairs of electrons. Choice C is also incorrect because it suggests the formation of a single bond, which only involves the sharing of one pair of electrons.
