The slideshow shows how a covalent bond forms between a hydrogen atom and a chlorine atom, making hydrogen chloride. A simple molecule contains only a few atoms, so the sizes of atoms and simple ...

In the water molecule, the oxygen and hydrogen atoms share electrons in covalent bonds. There are a total of 10 protons and 10 electrons, so the water molecule is neutral. The electron cloud model ...

It is relative to hydrogen which was assigned a value of 2.20 on the Pauling scale. In an oxygen (O2) molecule, both atoms have the same electronegativity. The electrons in the covalent bond are ...

Another reason is that these long skinny molecules are loosely packed together. Polyvinyl chloride is made up of carbon, hydrogen, and chlorine atoms. If you compare polyvinyl chloride to polyethylene ...
