Covalent solids Flashcards
Are covalent network solids typically brittle?
Yes, covalent network solids are generally brittle due to the strong and rigid covalent bonds throughout their structure.
Are covalent network solids malleable or ductile?
No, covalent network solids are typically not malleable or ductile due to their rigid and interconnected atomic structure.
Do covalent network solids have high or low melting points?
Covalent network solids generally have high melting points because breaking strong covalent bonds requires a significant amount of energy.
Are covalent network solids soluble in water?
Covalent network solids are usually insoluble in water, although some may dissolve in specific solvents.
Why are covalent network solids typically not malleable or ductile?
Covalent network solids have a rigid and interconnected atomic structure formed by strong covalent bonds. The directional nature of these bonds hinders the movement of atoms past each other, preventing malleability and ductility.
What type of bonding is prevalent in covalent network solids?
Covalent network solids are characterized by the presence of strong covalent bonds, where electrons are shared between adjacent atoms, forming an extended three-dimensional network.
Question: Why do covalent network solids often have high melting points?
Covalent network solids have high melting points because breaking the strong covalent bonds throughout their structure requires a substantial amount of energy.
