The [|**elements**] are placed in specific places because of the way they look and act.

It continues down the periodic table like that....

We found the eight most abundant elements...

match our jellybean patterns to another kind of visual picture - Mr Beaton's pie charts...

A perfect match! Element percentages by weight.

The "Shell Alphabet"

p = proton; n = neutron; e = electron.
|| ==Structure of an Atom...==

We built a model of an Oxygen atom...

 * ====Jellybean protons====
 * ====Marble neutrons====
 * ====Lollipop electrons - the handles reminded us that====

electrons can move in different directions.

....hmmm it's not very **stable!**

Building the model of oxygen...
Oxygen has only 6 electron lollipops in Shell 2.. It won't be completely happy until it has found 2 more electrons from somewhere... ||
