Chlorine gas (Cl2) has one single covalent
bond.
How many electrons do the chlorine atoms share

See explanation

Explanation:

In each chlorine atom, there are seven valence electrons. Recall that each chlorine atom only needs one electron in order to achieve the stable octet structure.

As a result of this, the chlorine atoms in Cl2 share two electrons contributed by each of the bonding atoms. By so doing, each atom achieves the stable octet as required by the octet rule.

explanation:

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.
