The mutual force of attraction between ions of opposite charges can best be described as

a. an ionic bond.
b. a polar covalent bond.
c. an electronegative bond.
d. a non-polar covalent bond.

A. an ionic bond.

Explanation:

An ionic bond is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element and forms cation and the element which accepts the electrons is known as electronegative element and forms the anion.The cations and anions being oppositely charged attract each other through strong coloumbic forces and form an ionic bond.

A covalent bond is formed when an element shares its valence electron with another element. This bond is formed between two non metals.

A polar covalent bond is defined as the bond which is formed when there is a difference of electronegativities between the atoms.

A non-polar covalent bond is defined as the bond which is formed when there is no difference of electronegativities between the atoms.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
