There you can find the metals, semi-conductor(s), non-metal(s), inert noble gas(ses), Halogens, Lanthanoides, Actinoids (rare earth elements) and transition metals. Please note that the elements do not show their natural relation towards each other as in the Periodic system. The unity for atomic mass is gram per mol. The lightest chemical element is Hydrogen and the heaviest is Hassium. The chemical elements ofįor chemistry students and teachers: The tabular chart on the right is arranged by Atomic mass (weight).

Uses of Magnesium: Used in alloys to make airplanes, missiles, racing bikes and other things that need light metals.Primary mining areas are Austria, China, Poland, Russia, USA, India, Greece and Canada. World production is around 350,000 tons per year. Sources of Magnesium: Usually obtained by electrolysis of melted magnesium chloride (MgCl 2) found in sea water. The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, Mu 1 × 103 kgmol1.Name Origin: Greek: From Magnesia a district of Thessaly. The Atomic masses are represented in the Atomic mass unit (u).Note: this data represents naturally occuring levels of elements in the typical human, it DOES NOT represent recommended daily allowances.
