Atoms of the same element, containing the same number of protons, but different numbers of neutrons, are known as isotopes. Isotopes of any given element all contain the same number of protons, so they have the same atomic number (for example, the atomic number of helium is always 2).

Answer:
Surface tension
Capillary action
Explanation:
Surface tension is the force acting along the surface of the liquid causing the liquid surface to behave like a stretched elastic skin. Surface tension causes the water drops that fall on a smooth surface to form rounded drops or beads.
If you touch a piece of paper to the drop, water appears to move up into the paper on its own due to capillarity. Capillarity is the tendency of a liquid to rise or fall in a narrow tube.
The correct order of increasing surface tension at a given temperature, CH(OH)CH₂ OH >CH₃CH₂CH₂OH>HOCH₂ CH₂ OH>HOCH₂
With higher intermolecular pressures, a molecule's surface tension rises. Here, every molecule that is there has a hydrogen bond. It is well known that as the number of O-H bonds in a given molecule increases, so does the degree of hydrogen bonding. Strong intermolecular forces are thought to exist in molecules with more H-bonds. Due to the hydrogen bonds between water molecules, it has the highest surface tension of any liquid, save for mercury. Water molecules near the liquid's surface that are in contact with air are held tightly together by surface tension to create an imperceptible film.
