question 13 of 30
in diamond, carbon atoms are bonded together by extended covalent bonds.
what type of solid is diamond?

a. network

b. metallic

c. ionic

d. amorphous

Explanation:

To determine the type of solid diamond is, we analyze each option:

• Option A: Network solids (also called covalent network solids) are held together by a continuous network of covalent bonds. Diamond consists of carbon atoms bonded by extended covalent bonds in a network structure.
• Option B: Metallic solids are held together by metallic bonds (involving delocalized electrons), which diamond does not have.
• Option C: Ionic solids are held together by ionic bonds (between cations and anions), and diamond has covalent bonds, not ionic.
• Option D: Amorphous solids lack a long - range ordered structure. Diamond has a highly ordered, crystalline structure.

So, based on the fact that diamond has a network of covalent bonds, it is a network solid.

Answer:

A. Network
