Periodic Table

First Genesis Spacecraft Samples Shipped to Researchers

Scientists at NASA's Johnson Space Center in Houston have shipped pieces of the Genesis polished aluminium collector to researchers at Washington University in St. Louis, marking the first distribution of a Genesis scientific sample from JSC since the science canister arrived there Oct. 4, 2004. The sample, the first to be allocated for Genesis early science analysis, may hold important evidence about the overall composition of the sun.

While much of the solar wind is hydrogen, it is hoped that Genesis captured samples of many elements in the periodic table. An analysis of these elements will help to determine the sun's composition in detail. Several important Genesis science objectives will be investigated as part of the Early Science Return, including studies of noble gas isotopes in bulk solar wind and nitrogen isotopes.


GoElemental! is an interactive open-air project in the city of Bath in the UK based around the periodic table of elements 6pm - 9pm, from the 17-19th December 2004. It is at St Michael's Square, opposite the Little Theatre Cinema, Bath, BA1 1SP, UK.

The work takes the format of a three-day interactive animation, to be projected onto a wall opposite the Little Cinema in St Michael's Square. Using their mobile phones, the audience will be able to text an element's name to a number provided at the show to find out where that element is used and what it does. On receiving the request, the projection will change and show a humorous or exciting animation of their chosen element.

GoElemental intends to whet people's curiosity about the scientific chemical elements, and introduce them to their everyday uses in an accessible and fun way. The idea behind the project is to spark a sense of wonder about the world around us.

GoElemental has been developed by Kerry Bradshaw, an MA student at Bath Spa University college, in collaboration with James Grierson from the Science department at Oxford Community school, and Peter Bradshaw, based in San Francisco, USA.

Position of hydrogen in the periodic table

I've taken the liberty of reproducing a CHMED-L post from Eric Scerri about hydrogen's position in the periodic table.

The position of hydrogen in the periodic system is a much debated topic. Authors have suggested groups I, VII and even IV over the years. Others opt from removing H from the main body of the table, along with He. The official journal of IUPAC, called Chemistry International, has been running some articles and comments on this issue.
