Concept explainers
(a)
Interpretation:
Classification of quartz into ionic, network, metallic, and molecular solid has to be determined.
Concept Introduction:
Crystalline solids can be classified as follows:
1. Ionic solids: As is evident from its name, ionic compounds are made up of ions. These ions have opposite charges on them and termed as cation while other with negative charge is termed as anion.
2. Metallic solids: Such solids consist of metallic bonds in between them. These bonds result from the interaction between positively charged atoms or electron deficient atoms and free electrons of same metal. These are formed between metal atoms.
3. Covalent solids: Such solids are also termed as network solids. These solids have covalent bonds between them. Since covalent bonds are present in ionic solids, these share electrons between bonded atoms.
4. Molecular solids: Van der Waals forces exist between molecular solids. These forces are quite weak as compared to the other forces. These are very soft with low melting points.
