2
|
Can draw or build a diagram of a molecule given a formula (but not attempting to show electrons in bonds)
|
Can build physical models and use the physical features of the objects (e.g. how many holes are in the atom ball or ion “key” etc.) to predict the chemical’s formula
|
Can draw abstract diagrams of molecules including electrons correctly predicting formulae in straightforward cases such as in simple ionic compounds
|
Can differentiate between covalent and ionic bonds
|
Can explain hydrogen bonding, van der Waal’s forces and isomerism (structural and stereo) using physical models or abstract diagrams
