Solution: Silicon carbide, SiC, has the three-dimensional structure shown in the figure.Would you expect the bonding in SiC to be predominantly ionic, metallic, or covalent?

Solution: Silicon carbide, SiC, has the three-dimensional structure shown in the figure.Would you expect the bonding in SiC to be predominantly ionic, metallic, or covalent?

Problem

Silicon carbide, SiC, has the three-dimensional structure shown in the figure

A diagram shows a cube with Si as the corners. Within the cube 4 Cs are each bonded to 4 additional Si atoms..

Would you expect the bonding in SiC to be predominantly ionic, metallic, or covalent?

Solution

We are asked to determine what to expect regarding the characteristic properties of the bonding in silicon carbide (SiC).

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 covalent bonds.

• Metallic solid: composed of metal and another metal or just a metal by itself.

• Covalent solid: also called a network solid where atoms are bonded by covalent bonds in a single continuous network.
