Beyond Core
Accomplished

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
