Born and raised in the city of London, Alexander Johnson studied biology and chemistry in college and went on to earn a PhD in biochemistry. ; Helps in the transportation of materials. Suppose oxygen was much less electronegative than it is, so that hydrogen-oxygen bonds were much less polar and hydrogen bonds could not form between water molecules.

Water readily dissociates ionic compounds, dissolves covalent molecules, and hydrates the smaller particles. In his writing, Alexander covers a wide range of topics, from cutting-edge medical research and technology to environmental science and space exploration. all 6 properties are a direct result of the polarity of water and its ability to form hydrogen bonds with other water molecules as well as other polar molecules. Sources/Usage: Public Domain. What happens to electrons when two hydrogen atoms combine with an oxygen atom? since water is covalent, oxygen hogs the electrons which makes it slightly negative, hydrogen do not see electrons as much which makes them slightly positive.

We will examine four emergent properties of water that con- tribute to Earths suitability as an environment for life: cohe- sive behavior, ability to moderate temperature, expansion upon freezing, and versatility as a solvent. This prevents freezing and ice formation in the protoplasm even when exposed to very low temperature. Because oxygen is more electronegative than hydrogen, it has a greater pull on the shared electrons. Cohesion causes the water molecules to stick together with such force that they defy gravity.
