Question

multiple choice question
which of the following best describes a covalent bond?
sharing of electrons between two atoms
attraction between the nuclei of two atoms
weak attraction between a slightly positive region of one atom and a slightly negative region of another
transfer of electrons between two atoms

Explanation:

A covalent bond is formed when two atoms share electrons to achieve a stable electron - configuration. The attraction between nuclei is not what defines a covalent bond. The weak attraction between slightly positive and negative regions of atoms is a description of intermolecular forces like dipole - dipole forces. The transfer of electrons between two atoms is characteristic of an ionic bond.

Answer:

Sharing of electrons between two atoms
