Template:Periodic table (metalloid): Difference between revisions

Recognition status, as metalloids, of some elements in the p-block of the standard periodic table. Elements with yellow green shading (B, Si, Ge, As, Sb, Te) are commonly recognised as metalloids. Elements with blue shading (Po, At) are inconsistently recognised, due to their status as metalloids being disputed. Selenium (Se), the element with pink shading, is still less commonly recognised as metalloid. Elements with pale yellow shading (C, Al) are rarely recognised as metalloids.

The grey staircase-shaped line, which passes between B-Al, Al-Si, Si-Ge, Ge-As, As-Sb, Sb-Te, Te-Po and Po-At, is a typical example of the arbitrary metal–nonmetal dividing line that can be found on some periodic tables. Germanium, if classified as a nonmetal, then appears to fall on the wrong side of the line. This is a result of the publicity this form of the line received in the late 1920s and early '30s. Germanium was thought to be a poorly conducting metal, up to at least the late 1930s.^[1]
