Publication of an Earth Scientist's Periodic Table of the Elements and their Ions

地质学（42）该项目支持出版地球科学家的元素及其离子周期表。ESPTEI是地球化学教学和理解方式的突破性变化。ESPTEI是一个大格式（14”x 36”）的彩色文档，可以在万维网http://www.gly.uga.edu/railsback/PT.html上看到。与传统的元素周期表不同，在传统的元素周期表中，元素是根据元素（不带电）形式的物质的性质和行为来组织的，ESPPEI是由带电形式（例如，Si 4+和S2-）组织的。该表还多次显示某些元素，以说明其多种天然存在的价态。这样做是因为地球科学家研究氧化和还原条件下的物质。该表的另一个特点是放置等离子势或电荷密度的轮廓。最后，ESPPEI的符号显示了土壤和自然沃茨中离子或带电形式的丰度，它们作为营养物的作用，以及它们在矿物、火成岩和深海结核中的存在。这些符号在很大程度上遵循了这个新重组的表格上的离子势轮廓，使矿物学，水地球化学，火成岩学，土壤地球化学，沉积地球化学，营养化学，甚至大气化学的许多趋势变得明显。

Geology (42)This project supports the publication of an Earth Scientist's Periodic Table of the Elements and Their Ions (ESPTEI). The ESPTEI is a ground-breaking change in the way geochemistry is being taught and understood. The ESPTEI is a large format (14" x 36") color document that can be seen on the World-Wide Web at http://www.gly.uga.edu/railsback/PT.html. Unlike the traditional periodic table where elements are organized according to the nature and behavior of elemental (uncharged) forms of matter, the ESPTEI is organized by charged forms (for example, Si4+ and S2-). The table also shows some elements multiple times to account for their multiple naturally occurring valence states. This is done because earth scientists study matter in both oxidizing and reducing conditions. Another feature of this table is the placement of contours of equal ionic potential or charge density. Finally, the ESPTEI has symbols showing the abundances of ions or charged forms in soils and in natural waters, their roles as nutrients, and their occurrences in minerals, igneous rocks, and deep-sea nodules. Those symbols largely follow the contours of ionic potential over this newly-reorganized table, allowing many trends in mineralogy, aqueous geochemistry, igneous petrology, soil geochemistry, sedimentary geochemistry, nutrient chemistry, and even atmospheric chemistry to become apparent.
