Answer to Question #298903 in Chemistry for jovie

Question

1. What makes network solids unique compared to other solids?

2. What is the importance of network solids in modern times? Explain your answer.

Answer 1

1. Network solids have similar properties to ionic solids. They are very hard, somewhat brittle solids with extremely high melting points (higher than 1,000 C or 1,800 F). Unlike ionic compounds, they do not dissolve in water, nor do they conduct electricity. Covalent bonds are extremely strong, so covalent solids are very hard.
2. Covalent Network Solids are giant covalent substances like diamond, graphite and silicon dioxide (silicon(IV) oxide).
