A plant dye is used in a question about reactions of organic functional groups. It is pertinent to the study of phenols. (NB I had previously ommited the reaction of phenol rings with bromine, now tried to include this)

Periodic table & electronic configuration

(0)
When I was teaching chemistry, we bought an 'interactive periodic table" which turned out to comprise laminated printed sheets of the first 22 elements with their electronic configurations, and some blue tac. This is my response to that. CLICK ON AN ELEMENT AND THE ELECTRONIC CONFIGURATION IS RETURNED. This compliments my drag & drop version. Please note: in order to provide a rich interactive experience, my interactive 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.

I made a simple labelling exercise for this GCSE chemistry practical. Now added a very simple additional worksheet

I made a simple information sheet about combustion of fuels and pollution. Because I wanted to.

A simple information sheet, with the emphasis on clarity. It may be useful to someone, somewhere.
Graph of boiling points of hydrides.

Graph of boiling points of hydrides.

The traditional textbook graph of this data is very confused. I feel that my presentation of the data emphasizes the role played by hydrogen bonding more clearly. The influence of atomic size on boiling point is also clearly shown by the bp of the noble gases.
