Well, I've been negligent. My last post had us learning about the periodic table. Since then we've learned about valence electrons,  Lewis dot diagrams, ionic and covalent bonding. This week we studied the types of chemical reactions. It seems to be easier to understand when we use students instead of symbols and chemical formulas in the bonding situations. So here are a few pictures from today. 

Sharing a pair of electrons to create HCl.

Aren't they the cutest Chlorine atoms.

Ionic bonding overcomes covalent.

Look at that single Copper atom

Sliver out on his own.

The same results from another class.

Two elements in two substances ......
