A test on chemical formulae that can be given to AS Chemistry students or students studying a level 3 science course that involves chemistry, e.g. will be useful for the new BTEC Applied Science Unit 1.
PowerPoint includes full list of ions that need to be learned in year 1 and also includes Roman numerals 1-10 which are often used in transition metal ions to indicate the positive charge on the ion formed.
Activities in formulae lessons (not included) include ionikits and ionikit worksheets (I think these worksheets are copyrighted and I’m not sure where they came from as they are quite old now).
A video I created to help students understand and learn formulae of ions. Explains from beginning what ions are, the general rules/trends and uses cards similar to the old ‘ionikits’ to illustrate the balancing of the charges. https://www.youtube.com/watch?v=pOsMci_o2dU
