Select the correct answer.

Which statement best explains how electrons form a covalent bond in a molecule?

A.

A pair of electrons splits so that each atom gets one electron.

B.

A pair of electrons belongs to two atoms at the same time.

C.

A pair of electrons is transferred from one atom to another atom.

D.

A pair of electrons moves from a lower energy level to a higher energy level.

E.

A pair of electrons drifts freely from one molecule to another.

The answer to your question is:

Explanation:

Covalent bonding is the process of sharing a pair of electrons between to atoms so they become stable.

A. In fact a process of split a pair of electrons do not happen in nature, there is no bonding that behaves in this way.

B. This is a definition of covalent bonding, in this bond, the elements share a pair of electrons to complete 8 electrons in their outermost shell.

C. The bond described here is Ionic bonding in which one element loses electrons and the other gains them.

D. The process describe here is not about any kind of bonding.

E. This do not happen in a covalent bonding, it could be the description of metallic bonding.
