Designed to make learning chemistry much easier and a whole lot more fun, this title features elements that show you a different kind of periodic table. (Gardners)Basher SimonKingfisher
The first part of this book shows how the periodic table is constructed on the basis of the atomic\nstructures of the elements, and the later chapters, using the periodic table as central theme, describe the physical and chemical properties of the elements and their compounds. For the second...
The periodic table is a system that scientists use to organize and classify chemical elements. 元素周期表是科学家用来记录和分类化学元素的系统。 Originally, many scientists tried to sort the elements by properties. 最初,许多科学家试图按性质对元素进行分类。 One of the early models of the periodic...

THE PERIODIC TABLE
The definitive online periodic table reference site including technical data, and photographs and descriptions of thousands of samples of the chemical elements.
The standard form of the periodic table shown here includes periods (shown horizontally) and groups (shown vertically). The properties of elements in groups are similar in some respects to each other. There is no one single or best structure for the periodic table but by whatever consensus ther...

原文定位:Um, actually, that reminds me of a ... of a very good example of all these, element 43. See on the table, the symbols for elements 42 and 44. Well, in early versions of the table, there was no symbol for an element 43 protons because no element with 43 protons had been...
