Molecules

Today we explored what a molecule is. This is a video that explains it really well.

 A molecule is two (or more) atoms that join and form a bond. This bond is formed by the atoms sharing their electrons.

Some molecules are quite simple like water which is H20 (2 hydrogen atoms and 1 oxygen atom)

  Some are more complex like table sugar which is C12H22O11.

We discussed how putting different atoms together can be just a mixture. It becomes a molecule when a chemical reaction happens. We looked at the following video to show how hydrogen and oxygen can be combined to make water.

We also looked at this video showing how a molecule can be returned to separate atoms.
