In your own words, explain how liquid water becomes solid ice. In your explanation be sure to use the following terms: thermal energy, particle motion, and temperature.

When liquid water loses thermal energy, it undergoes freezing : changing state from a liquid to a solid. We see many examples of this in everyday life. Puddles, ponds, lakes, and even parts of oceans freeze when the water becomes cold enough. At low temperatures, Earth's surface water freezes and forms solid ice.

Freezing is the process that causes a substance to change from a liquid to a solid. Freezing occurs when the molecules of a liquid slow down enough that their attractions cause them to arrange themselves into fixed positions as a solid.

They are all full and don't need any more electrons in there outer shell.
