Practice calculating the ionic formula from the name of the compound in the style of a game. This chemistry based app includes hundreds of practice questions using a range of charged ions. Choose from GCSE level or A-level questions to suit your level of learning.
The game covers not only how to combine ions to give the ionic formula of a compound, but also ensures understanding of how charges relate to the periodic table, for example that group one elements form only +1 ions, therefore ensuring that the chemical knowledge behind working out a compound formula is understood.
Select from two modes of play, either type the answer directly or drag and drop from the selection given. Perfect for playing on the move. The selection can be altered between easy play (where only relevant elements are given) for more challenging play (where a range of elements with similar symbols are given).
Practice really does make perfect and this game allows students to get to grips with the basics of ionic formulae before taking that understanding to a higher level.
