An arsenic atom in organic compounds is attractive among group 15 elements. It has much higher inversion energy than a nitrogen atom, and can be utilized as a stereocenter. Organic compounds having trivalent arsenic atoms are air-stable unlikely to the corresponding phosphorus analogues.Hiroaki ...
In theperiodic table of the elements, arsenic is No. 33. An arsenic atom has 33 electrons and 33 protons with five valence electrons (those that can participate in forming chemical bonds with other electrons) in its outer shell. Arsenic is a crystallinemetalloidfound in the Earth's crust, b...
Yellow arsenic is soft and waxy, and somewhat similar to tetraphosphorus (P4).[19] Both have four atoms arranged in a tetrahedral structure in which each atom is bound to each of the other three atoms by a single bond. This unstable allotrope, being molecular, is the most volatile, least ...

Yellow arsenic (As4) is soft and waxy, not unlike P4. Both have four atoms arranged in a tetrahedral structure in which each atom is bound to each of the other three atoms by a single bond, resulting in very high ring strain and instability. This form of arsenic is the least stable, ...
(Sb and Bi) as well. The rhombohedral structure of arsenic is known asgray arsenic(g-As) where it is consisted of six atoms forming a ring in chair conformations. Each arsenic atom is bound to three neighboring arsenic atoms in the same layer and three atoms on the next layer creating ...
organic arsenicalsThis chapter first focuses on metabolic processes that convert inorganic arsenic into methylated oxyarsenical species; that is, compounds in which an arsenic atom is bound to one or more methyl groups and one or more oxygen atoms, and on the toxicological significance of the ...
Inorganic compounds do not contain an arsenic–carbon bond while organic compounds do. 2.7 Color/Form Silver to black 2.8 Decomposition When arsenic is heated in air it will burn and form a white smoke consisting of arsenic trioxide (As2O3). 2.9 Heat of Vaporization 11.2 kcal/g-atom 2.10 ...
