IB Chemistry 2.1.1 Ion formation Questions
Practise predicting whether atoms gain or lose electrons, then deducing ion charges, electron configurations and ionic formulae from simple species data.
How this is tested
- deduce whether atoms gain or lose electrons to form the most stable ion
- identify ion charges and electron configurations in compounds such as calcium nitride
- deduce ionic formulae by balancing charges, as in indium sulfate
