The Chemogenesis Webbook Unlike chemistry textbooks printed on paper, this webbook contains dynamic Synthlet and Database pages that explore and make predictions about aspects of chemical structure & reactivity and have embedded reaction chemistry YouTube Videos. Thanks go to the authors of web sites linked to from these pages, to members of the International Society for the Philosophy of Chemistry (ISPC) and to the members of the ChemEd internet discussion list who have answered my many questions and synthesized such interesting postings. This web book is being continually updated. Please send comments, link suggestions, factual errors, browser problems, bug & broken link reports, etc., to the author:
Elements & Periodic Table Now we're getting to the heart and soul of the way the Universe works. You know that a generic atom has some protons and neutrons in the nucleus and some electrons zipping around in orbitals. When those pieces start combining in specific numbers, you can build atoms with recognizable traits. Practical Chemistry This website is for teachers of chemistry in schools and colleges. It is a collection of experiments that demonstrate a wide range of chemical concepts and processes. Some of the experiments can be used as starting-points for investigations or for enhancement activities. Many have links to carefully selected further reading and all include information and guidance for technicians. Chemistry is a practical science. Applying: Brochure Download Applications Early application is advisable as places on courses and in colleges are limited and allocated on a first-come, first-served basis. Online application

White Tea Vs. Green Tea - Difference Between White Tea And Green Tea Almost everyone has a fair idea of the health benefits of green tea. For the health conscious, green tea is a part and parcel of the daily routine. And why not, when for decades people have been bombarded with advertisements extolling the medicinal properties of green tea, and rightly so. The Compound Interest Periodic Table of Data Today’s graphic is one that I’ve been working on over the past couple of weeks. Every chemistry classroom has a Periodic Table, but it’s often a drab affair; considering it’s one of the cornerstones of chemistry, I thought I’d attempt to produce a more dynamic looking version. The result is the above table – each element is shown within a circle that contains a variety of data pertaining to that element. The data shown for each element is as follows: Melting point in degrees celsius.Boiling point in degrees celsius.First ionisation energy in kilojoules per mole.Atomic radius in angstroms.Electronegativity (on the Pauling scale).Density (in grams per centimetre cubed (g/L for gases)).
