Each hydrogen atom has one valence electron, but it needs two electrons to be stable. How can both hydrogen atoms each achieve a stable configuration

Through Covalent Bonding

Explanation:

Both Hydrogen can achieve a stable configuration with 2 electrons by each sharing their electrons.

The name of this bonding is called covalent bonding. In this type of bonding, each participating entity (in this case, the hydrogen atoms) donates their valence electrons (the one valence electron in the hydrogen atoms) then share the total electrons (1 + 1 = 2).

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.
