Network Covalent Solids: Which is Not an Example?
Which of the following is not an example of a network covalent solid?
a. iron
b. diamond
c. graphite
d. SiC (silicon carbide)
e. SiO2 (sand)
Answer:
Iron is not an example of a network covalent solid as it forms metallic bonds instead of covalent bonds to hold its atoms together.
To determine which of the following options is not an example of a network covalent solid, let's first understand what a network covalent solid is. A network covalent solid is a solid in which the atoms are held together by a network of strong covalent bonds.
Out of the given options, iron is not an example of a network covalent solid. Iron forms metallic bonds instead of covalent bonds to hold its atoms together.
Therefore, the correct answer is a. iron.
