Neutral Salts can be fun

A worksheet for writing formulae of ionic compounds. Some explanation on the front, and plenty of examples to do on the back. The knowledge of the structure of ions is crucial to success in chemistry. In black and white for easy photocopying. I have had to completely rework this in affinity publisher due to my own fault, a spelling mistake in quark express (a program which is of no use to me any more) Sorry for anyone who bought it. I know to spell exercise. Really Update: answers also provided and cosmetic improvement. I do hope this is useful to someone.

Recognising the Type of Reaction

(0)
One of the most useful skills in answering many GCSE chemistry questions is to work out what type of reaction is involved in the question. This helps you work out what the products may be, but also answer other questions about the reaction. Students often find this very difficult, mainly due to a lack of practice and experience. This simple information sheet with questions at the back is in black and white so can be readily photocopied.

I made a very simple ‘fill in the gaps’ worksheet. It may be useful because it focuses on the adjectival and noun words in this topic.

A simple, photocopiable worksheet (black and white!) that gives practice at interpreting simple chemical formulae. The examples get harder as you proceed. It is comprised of two pages of examples. It is suitable for KS3 and KS4 students. It could be used in class or for homework.

Chemical Analysis wordsearch

A simple wordsearch on 1 side of A4. It is quite a challenge! For GCSE chemists. ( I have now removed an error which had two letters in one box and one box with a space. I had to make it bigger and spread the puzzle onto two sides, one side with clues and one with the puzzle grid. Apologies to those who bought the defective version- contact me for a replacement)

Interactive electronic configuration

4 Resources
Drag and drop resources to reinforce electronic configuration in atoms and how this underpins the layout of the periodic table. Please note: in order to provide a rich interactive experience, my drag & drop resources are mini-web sites local to your computer. After unzipping, they comprise a folder containing the main .html file and another folder containing the graphic resources and my coding to make the resource work. Double click on the .html file and the resource will work. If, however , you move or delete any of the files from this hierarchy, the resource will not work.
