Arsenic, atomic number 33 lies in between phosphorus and antimony in group 15, the so called Nitrogen group of the periodic table. Members of the group including of course nitrogen, along with arsenic, phosphorous, antimony and bismuth are particularly stable in compounds because they tend to form double or triple covalent bonds.

Aug 11, 2023 1st shell can hold 2 electrons. 2nd shell can hold 8 electrons. 3rd shell can hold 18 electrons. 4th shell can hold 32 electrons. Now the atomic number of arsenic (As) is 33. Hence the arsenic element has electrons arrangement 2, 8, 18, 5. This electron arrangement indicates that the outermost orbit of Arsenic element (As) has 5 electrons.
Properties. The element is a steel gray, very brittle, crystalline, semimetallic solid; it tarnishes in air, and when it is heated it rapidly oxidizes to arsenous oxide, which smells of garlic. Arsenic and its compounds are poisonous. Uses. Arsenic is used in bronzing, pyrotechny, and for hardening and improving the sphericity of shot.
