Boron, for example, will act like a nonmetal when interacting with the volatile element sodium but will behave like a metal element when interacting with fluorine. Most authors recognise one or the other, or both, as metalloids; Herman, Hoffmann and Ashcroft, on the basis of relativistic modelling, predict astatine will be a monatomic metal. Polonium, for example, is dangerous due to its toxicity and radioactivity. Also, there are examples of substances that are not elements and a … Ga,Ge,Si are few examples for metalloids. Selenium, in particular, is commonly designated as a metalloid in environmental chemistry[n 7] on account of similarities in its aquatic chemistry with that of arsenic and antimony.

Most metalloids are semiconductors–they have a small electrical conductivity which increases as their temperature is raised or impurities are added. They even carry electric charge that makes them suitable for use in computers and calculators. [n 2] The staircase-shaped line is a typical example of the arbitrary metal–nonmetal dividing line found on some periodic tables. Unlike other families of elements such as the noble gases, alkali metals, and halogens, the metalloids form a diagonal line on the periodic table rather than a vertical line.
