Recognition status, as metalloids, of some elements in the p-block of the periodic table. Metal, Nonmetal, or Metalloid? The diamond form of carbon looks and behaves as a nonmetal, while the graphite allotrope has a metallic luster and acts as an electrical semiconductor and so is a metalloid. All the elements in gray are metals. Generally, nonmetals have low melting and boiling points. The elements of this group have four electrons in the valence shell. If hydrogen is inhaled in small concentrations it can cause symptoms like headache, nausea, irritation in skin and eye, convulsions. However, it varies greatly from the. . Louli. So, we can say that the physical and chemical properties of boron are in between metal and nonmetal so it is a metalloid. Is phosphorous a metal metalloid or nonmetal?
