Arsenic is a chemical element with the symbol As and the atomic number 33. It is a metalloid and one of the pnictogens, and therefore shares many properties with its group 15 neighbors phosphorus and antimony. Arsenic is a notoriously toxic heavy metal.
The group 1 alkali metals and the group 2, alkaline earth metals, form arsenides with isolated arsenic atoms.They form upon heating arsenic powder with excess sodium gives sodium arsenide (Na 3 As).
Alchemical symbols were used to denote chemical elements and compounds, as well as alchemical apparatus and processes, until the 18th century. Although notation was ...
Expressing resonance when drawing Lewis structures may be done either by drawing each of the possible resonance forms and placing double-headed arrows between them or by using dashed lines to represent the partial bonds (although the latter is a good representation of the resonance hybrid which is not, formally speaking, a Lewis structure).
In its standard state arsine is a colorless, denser-than-air gas that is slightly soluble in water (2% at 20 °C) [1] and in many organic solvents as well. [citation needed] Arsine itself is odorless, [5] but it oxidizes in air and this creates a slight garlic or fish-like scent when the compound is present above 0.5 ppm. [6]
Arsenic is a chemical element that has the symbol As and atomic number 33. This pyramidal molecule is the only known binary arsenic bromide. AsBr 3 is noteworthy for its very high refractive index of approximately 2.3. It also has a very high diamagnetic susceptibility. [2] The compound exists as colourless deliquescent crystals that fume in ...
Chemical symbols are the abbreviations used in chemistry, mainly for chemical elements; but also for functional groups, chemical compounds, and other entities. Element symbols for chemical elements, also known as atomic symbols, normally consist of one or two letters from the Latin alphabet and are written with the first letter capitalised.
Yellow spherules of halilsarpite, an arsenate arsenite mineral, on orange-brown smolyaninovite. An arsenate arsenite is a chemical compound or salt that contains arsenate and arsenite anions (AsO 3 3-and AsO 4 3-).
