The amazing properties of water
Water is the most abundant compound on Earth's surface, covering about 70 percent of the planet.
In nature, water exists in liquid, solid, and gaseous states.Many substances dissolve in water and it is commonly referred to as the universal solvent.
Water is the chemical substance with chemical formula H2O
The water molecule, as a whole, has 10 protons and 10 electrons, so it is neutral.
In a water molecule, the oxygen atom and hydrogen atoms share electrons in covalent bonds, but the sharing is not equal.
In the covalent bond between oxygen and hydrogen, the oxygen atom attracts electrons a bit more strongly than the hydrogen atoms.
The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms.
When a neutral molecule has a positive area at one end and a negative area at the other, it is a polar molecule.
Water molecules attract one another based on the attraction between the positive end of one water molecule and the negative end of another.

Is there a difference in density between fresh water and salt water?

Hot water floats on cold, but..why?
