Eureka! Episode 22 - AtomsThis program explains that molecules are made up of atoms. In pure metals, all the atoms are arranged separately in a lattice-work pattern, but in most non-metals, liquids, and gases, the atoms are bunched together into molecules.
Using an animated model of an atom, Eureka! illustrates how electrons whiz so quickly round the nucleus that they appear to form layers
Eureka! looks at the process of conduction, explaining that the application of heat to an object makes the molecules or atoms vibrate faster and cause a sort of "domino effect.
