Who am I?
In Spring Semester I teach CHEM 409, Chemistry Research Seminar, and in that class we partner with WikiEdu to do edits to Chemistry and Biochemistry related pages on wikipedia. I am also in the pool of mentors for faculty teaching classes using WikiEdu.

Here is how to do it

Article evaluation
I am choosing the article on Ronald Gillespie - one of my former postdoctoral advisers.

The paragraph describing his work is extensive on the last 10 or so years of his active academic life, but ignores many of the contributions he made to noble gas and fluorine chemistry he made before moving into theoretical chemistry. There is a lot about LCP which is a theory which never really gained any traction - it may have been written by Paul Popelier or Peter Robinson (it appears Peter is still alive and living in England) who are about the only two people who use the theory).

There are only three references, but all are correct.

There is very little on the talk page, though it is being supported by a project biography. It is considered a stub.

I left a comment on the Talk page about the imbalance between LCP and VSEPR/fluorine chemistry

Here is a paper on the significance of VSEPR and Gillespie

Infobox references Tungstic acid refers to hydrated forms of tungsten trioxide, WO3. The simplest form, the monohydrate, is WO3·H2O, H2WO4. The dihydrate WO3·2H2O is also known. The solid-state structure of WO3·H2O consists of layers of octahedrally coordinated WO5(H2O) units where 4 vertices are shared.[1] The dihydrate has the same layer structure with the extra H2O molecule intercalated between the layers.[1] The monohydrate is a yellow solid and insoluble in water. The classical name for this acid is 'acid of wolfram'. Salts of tungstic acid are tungstates.

The acid was discovered by Carl Wilhelm Scheele in 1781.[2]

Preparation Tungstic acid is obtained by the action of strong acids on solutions of alkali metallic tungstates. It may also be prepared from the reaction between hydrogen carbonate and sodium tungstate. It can also be obtained from pure tungsten by reaction with hydrogen peroxide.[3]

Uses It is used as a mordant and a dye in textiles.
