1. Ions and their Chemical Formulae
Ion Model (Whiteboard) by Javalab
In an ionic compound, the number of positive charges in the cations are balanced by the number of negative charges in the anions.
​
This interactive simulation helps you to visualise the ratio of cations and anions in an ionic compound.

Three games to level up your formula writing!
1) Ions Matchmaker: gives students formulae of positive and negative ions and requires them to type the formula of the ionic compound
​
2) Formula Feast: allows students to match ions to name compounds without typing anything (it's based on WriteFormula)
​
3) Formula Writing Challenge: includes covalent and ionic compounds, without giving formulae of any ions
