18.3 Structure and General Properties of the Metalloids – …
Silicon reacts with halogens at high temperatures, forming volatile tetrahalides, such as SiF 4. Unlike carbon, silicon does not readily form double or triple bonds. Silicon compounds of the general formula SiX 4, where X is a highly electronegative group, can act as Lewis acids to form six-coordinate silicon.

The name silicon is derived from the Latin word for flint, silex. The metalloid silicon readily forms compounds containing Si-O-Si bonds, which are of prime importance in the mineral world. This bonding capability is in contrast to the nonmetal carbon, whose ability
Silicon carbide, SiC, has the three-dimens | Clutch Prep
Silicon carbide, also known as carborundum, is a unique compound of carbon and silicon and is one of the hardest available materials. Recall that the types of solids are: • Ionic solid: composed of a metal and a nonmetal as ions. • Molecular solid: composed of .
Carbide - WikiMili, The Best Wikipedia Reader
In chemistry, a carbide usually describes a compound composed of carbon and a metal. In metallurgy, carbiding or carburizing is the process for producing carbide coatings on a metal piece. For a long time the non-stoichiometric phases were believed to be disordered with a random filling of the interstices, however short and longer range ordering has been detected.

Because of the diagonal relationship between boron and silicon, metal silicides and metal borides exhibit many similarities. Although metal silicides have structures that are as complex as those of the metal borides and carbides, few silicides are structurally similar to the corresponding borides due to the significantly larger size of Si (atomic radius 111 pm versus 87 pm for B).
