2019-4-23 · The characteristic properties of metals and nonmetals are quite distinct, as shown in the table below. Metalloids, straddling the metal-nonmetal border, are mostly distinct from either, but in a few properties resele one or the other, as shown in the shading of the metalloid column below and summarized in the small table at the top of this section.

Silicon - Wikipedia

2019-4-23 · Silicon is a chemical element with syol Si and atomic nuer 14. It is a hard and brittle crystalline solid with a blue-grey metallic lustre; and it is a tetravalent metalloid and semiconductor. It is a meer of group 14 in the periodic table: carbon is above it; and germanium, tin, and lead are below it. It is relatively unreactive

Metal - Wikipedia

2019-4-23 · A metal (from Greek μέταλλον métallon, "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically malleable (they can be hammered into thin sheets) or ductile (can be drawn into wires). A metal may be a chemical element such as iron, or an alloy such as

Carbon - Wikipedia

2019-4-28 · Carbon is the fourth most abundant chemical element in the observable universe by mass after hydrogen, helium, and oxygen. Carbon is abundant in the Sun, stars, comets, and in the atmospheres of most planets. Some meteorites contain microscopic diamonds that were formed when the solar system was still a protoplanetary disk.
