Model ionic bonding with moving electrons!
Ionic bonding is easy to understand with our unique molecular model that shows how electrons behave during bond formation.
Download and print as many times as you want - forever at no extra cost!
Your students first build their easy to make paper models of atoms and electrons. They use these to form ions by moving electrons between the atoms.
The differently coloured electrons make it easy to see how the ionic bonds are formed. The models can be used to show NaCl, MgO, MgCl2, Na2O, CaCl2.
The following polyatomic ions can be made with the model: hydroxide, nitrate, carbonate and sulfate. These can be used to make: Ca(OH)2, Mg(NO3)2, Al(NO3)3, Na2CO3, MgCO3, CaCO3, CaSO4.
Optional extension to show a giant ionic lattice is included.
Includes full colour Powerpoint class presentation!
Takes about 30 minutes! Model atom diameter 10cm/4in
