Hydrogen has three isotopes, 1h, 2h, and 3h. what is the difference between these three isotopes?
a. the number of protons ranges from 1 to 3.
b. the number of electrons ranges from 1 to 3.
c. the number of neutrons ranges from 0 to 2.
d. the number of protons ranges from 0 to 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.

hope this .

the answer is c.the valence of the atoms combine .
