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 1999, Pure Appl. Chem., Vol. 73, No. 4 (2001) 667-683) CONTENT: 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.

The calculator contains a list with task history, storing all the recent inputs and results. ● 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. '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) Visual Basic programs ● EniG. Periodic Table of the Elements 2.11 contains the basic data about the element in 7 languages (Croatian, English, French, http://www.ktf-split.hr/periodni/en/ (2 de 3)28/02/2006 14:35:24 Periodic Table of the Elements 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.

The origin of the name comes from the Greek words hydroand genesmeaning waterand generate. It is colourless, odourless gas, burns and forms explosive mixtures in air. Reacts violently with oxidants. Hydrogen is the most abundant element in the universe.
