Arsenic is an element that has an atomic number 33. Its standard atomic weight is 74.921 and it is represented by the symbol As. It is in group 15 (Nitrogen family) and period 4 of the periodic table. Arsenic is a metalloid and a p-block element. Its electronic configuration is 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d10, 4p3. It has 33 electrons, 33 protons and 42 neutrons. The numbers of neutrons vary in different isotopes. Arsenic has a density of 5.727 g/cm3. It has a grey-metallic appearance. The three most common allotropes are grey, yellow and black. The electronegativity of Arsenic is 2.18 (Pauling scale) and its oxidation state is −3, −2, −1, 0, +1, +2, +3, +4, +5. The oxidation states changes depending on the properties of reacting atom or species. The 1st ionization energy required for Arsenic is 947.0 kJ/mol.
Arsenic is a monoisotopic element. There are some 33 isotopes of Arsenic in which only one Arsenic-75 is stable. The isolation of Arsenic was described by Jabir ibn Hayyan in 815 AD. Later on, Albertus Magnus isolated Arsenic from soap heating it with arsenic trisulfide in 1250 AD.
Arsenic is considered 53 abundant element in Earth's crust. China is producing 70% of the world White Arsenic. Followed by Morocco, Russia, and Belgium.
Arsenic has a wide range of uses Some of the following are.
It is used in agriculture because of its toxicity it is used as a wood preservative. It is used as insecticides (lead hydrogen arsenate) and fungicides. It is used as a feed additive to increase the weight of poultry and swine production. Gallium arsenide is used in semiconductors and integrated circuits. It is used for taxonomic sample preservation.
