Which element of group 15 does not show allotropy(options are in image)

Answered by admin @ 23/08/2021

Answer:

nitrogen

Explanation:

allotroph of phosphorous is rather complex but essentially , there are three allotropic forms known as white, red and black phosphorous . Arsenic and antimony also exhibit allotrophy , an unstable form of each element ,structurally similar to that of white phosphorus being formed by rapid condensation of their capours. this unstable form is readily transformed into a denser allotrope which is metallic and similar in structure to that of black phosphorus. Bismuth does not exhibit allotroph and adopts this latter structure(i.e. the layer structure). <br> Bismuth is unusual, because the expands when it forms the silid. This unsual behaviour
