ARTIFICIALI

Relative atomic mass is shown with five significant figures. For the precise value of the atomic mass you must click on an element symbol in periodic table. For elements have no stable nuclides, the value enclosed in brackets indicates the mass number of the longest-lived isotope of the element. However three such elements (Th, Pa and U) do have a characteristic terrestrial isotopic composition, and for these an atomic weight is tabulated (Atomic Weights of the Elements 2005, Pure Appl. Chem., Vol. 78, No. 11 (2006) 2051-2066).

Glossary of chemical terms	Glossary of chemical terms contain a brief definitions of selected terms of importance in chemistry and related fields of science. Individual chemical compounds are not included. It is composed of two parts: appendixes dictionary A \| B \| C \| D \| E \| F \| G \| H \| I \| J \| K \| L M \| N \| O \| P \| R \| S \| T \| U \| V \| X \| Z

css - Tavola periodica degli elementi	Periodic table of the elements contains the basic data about the elements in five languages: Inglesi (Editors: Aditya Vardhan, Eni Generalic) Francesi (Editor: Michel Ditria) Croato (Editors: Eni Generalic, Marija Bralic, Slobodan Brinic) Tedesco (Editor: Marc Hens) Italiano (Editor: editors wanted) The further information of each element can be found by periodic table alphabetical listing names alphabetical listing of symbols ASCII periodic table PSE.Menu is a small remote control for Periodic table of the elements. It opens in a separate window and the selected page is loaded in a parent window.

Printable periodic table	Periodic table of the elements is prepared for prints in Portable Document Format (PDF) in two versions black white version for laser printers colour version for colour printers 3D paper models of crystal systems (cubic, tetragonal, orthorhombic, hexagonal, rhombohedral, monoclinic and triclinic)

JavaScript programs	This JavaScript programs will work for both Netscape and MSIE users, so you need to get Netscape Navigator 2.0, Microsoft Internet Explorer 3.0 or later. Pages are best viewed with Microsoft Internet Explorer 4.0 or higher. Calcolatrice scientifica per i chimici Calcolatrice scientifica per i chimici con un taccuino pieno funzionamento di JavaScript calcolatrice. Questa calcolatrice puo essere usato come calcolatrice scientifica comune (peccato, cos, di log, potenza, radice, memoria), ma include anche un peso molecolare calcolatrice e le tabelle con le varie costanti fisiche e chimiche. La calcolatrice contiene un elenco compito con la storia, di memorizzare tutte le recenti ingressi e risultati. Calcolatrice scientifica visualizza i numeri arrotondati di un determinato numero di decimali. Scientific calculator Sci.Calc is a fully-functioning JavaScript calculator that contain of practically any common and many advanced calculator functions (cosine, sine, tangent, power, square root, exponents, etc.). Molar mass calculator Molar mass calculator is an expression calculator for fast calculation of molecular weight of compounds. The program translates the texts with chemical element symbols or without them into a mathematical expression and calculates them.

Visual Basic programs	'Tools & Toys' contains some programmes for chemists (and non-chemist). You can download a programmes in two self-install copy: one with all the files needed and other without Visual Basic library. EniG. Chemistry Assistant 2.4 is an expression calculator for fast calculation of molecular weight of compounds by simple entry of chemical formula (the element symbols can be written in lowercase letters). The calculator also provides a list of common physical constants and performs various conversions between English and metric units. (Update: 2002/12/12) EniG. Periodic Table of the Elements 2.11 contains the basic data about the element in 7 languages (Croatian, English, French, German, Italian, Portuguese, and Spanish). It shows the change of physical condition with the change of temperature. The language, the speed of temperature changes or the exchange of elements can be adjusted by configuration file. The calculating module from the programme Chemistry Assistant has been integrated. (Update: 2003/03/28)
