The Water Molecule H 2 O Water is a polar molecule – It has a positive and a negative end. – Overall neutral charge
Polar Molecules Electrons are pulled closer to larger nucleus.
Hydrogen Bonds Attraction of partial opposite charges between hydrogen and oxygen [for example] Polar molecules attract to other polar molecules.
Waters polarity allows it to dissolve sodium chloride [NaCl] and many other ionic and polar compounds.
Cohesion Attraction between molecules of the same substance. – Ex. Water beading up on smooth surface. – Try floating a metal pin on water.
Adhesion Attraction between molecules of different substances. – Capillary action
Water Water expands when it freezes. So ice is less dense than liquid water and it floats.
