Cosmochemical Periodic Table of the Elements in the Solar System - In cosmochemistry, the Cosmochemical Periodic Table of the Elements in the Solar System is a periodic table that lists all known chemical elements. In addition, it supplements the standard periodic table with extra information for each element, including its condensation temperature,
Periodic table - The periodic table of the chemical elements is a tabular method of displaying the chemical elements, first devised in 1869 by the Russian chemist Dmitri Mendeleev. Mendeleev intended the table to illustrate recurring ("periodic") trends in the properties of the elements.
Periodic table group - A periodic table group is a vertical column in the periodic table of the chemical elements. There are 18 groups in the standard periodic table.
Chalcogen - The chalcogens (with the "ch" pronounced with a hard "c" as in "chemistry") are the name for the periodic table group 16 (old-style: VIB or VIA) in the periodic table. It is sometimes known as the oxygen family. It consists of the elements oxygen (O), sulfur (S), selenium (Se), tellurium (Te), the radioactive polonium (Po), and the synthetic ununhexium (Uuh). The compounds of the heavier chalcogens (particularly the sulfides, selenides, and tellurides) are collectively known as chalcogenides. Unless grouped with ...

'Symbol Number' - ... numbering is a function which assigns to each symbol and formula of some formal language a unique natural number called a Gödel number (GN). The concept was first used by Kurt Gödel for the proof of his incompleteness theorem. Period-after-opening symbol - [period after opening symbol or PAO symbol is a graphic symbol] that identifies the useful lifetime of a [[cosmetics product after its package has been opened for the first time. It depicts an open cosmetics pot and is used together ...

The first few predate any written record. 1741 Discovered independently by Antonio de Ulloa (publishe... The elements are listed generally in the order in which they were first isolated as the pure element, rather than as a compound (some such as boron were known to be elements decades before they could be isolated from their compounds). Each book includes sidebars with interesting facts and easy-to-do experiments along with a glossary, an index, and a "To Find Out More" section listing books, organizations, and websites.
