Sodium(Na) atomic and molecular weight, atomic number and elemental symbolSodium is a Block S, Group 1, Period 3 element. The number of electrons in each of Sodium's shells is 2, 8, 1 and its electronic configuration is [Ne] 3s1. In its elemental form sodium's CAS number is 7440-23-5. The sodium atom has a radius of 185.8.pm and it's Van der Waalsradius is 227.pm. Sodium is not toxic but skin contact may cause irritation and burns. Sodium is primarily used in its metallic form in the production of Sodium Bohr Modelchemical esters and in the manufacturing of various other organic compounds. The metal is used in the alloy of tin, nickel and copper for its structural characteristics. Sodium is availableas metal and compounds with purities from 99% to 99.9999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. High purity sodium compounds are used as reducing agents. Sodium compounds are used in low tech applications throughout industry. Sodium was first discovered by Sir Humphrey Davy in 1807. The name Sodium comes from the Latin word "natrium" which means sodium carbonate. See Sodium research below.

Arsenic(As) atomic and molecular weight, atomic number and elemental symbolArsenic is a Block P, Group 15, Period 4 element. The number of electrons in each of Arsenic's shells is 2, 8, 18, 5 and its electronic configuration is [Ar] 3d10 4s2 4p3. In its elemental form arsenic's CAS number is 1327-53-3.Elemental Arsenic The arsenic atom has a radius of 124.5.pm and it's Van der Waals radius is 185.pm. Arsenic in the organic form is not harmful but in the inorganic form it is extremely toxic even in very small amounts. Arsenic has numerous applications as a semiconductor and other electronic applications as Indium arsenide, silicon arsenide and tin arsenidea. Arsenic is finding increasing uses as a doping agent in solid-state devices such as transistors. Gallium arsenide is used as a laser material to convert electricity directly into coherent light. Arsenic is used in bronzing and for hardening and improving the sphericity of shot. Arsenic is available as metal and compounds with purities from 99% to 99.9999% (ACS grade to ultra-high purity); metals in Arsenic Bohr Modelthe form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Arsenic information, including Technical Data, Safety Data and its High Purity properties, research, applications and other useful facts are discussed here. Scientific facts such as the atomic structure, ionization energy, abundance on Earth, conductivity and thermal properties are included. See Arsenic research below.
