(a)
Interpretation:
The behavior of a metal gold when deformed by a hammer strike has to be described and also a reason behind this behavior has to be explained.
Concept introduction:
Types of solids and their properties:
Ionic solid | Metallic Solid | Molecular Solid | Network Solid | Amorphous Solid | |
Formed from | Reactive metals and reactive non metals | Elements that are metals | Non-metals combined with non-metals | Group IVA elements; many compounds containing silicon and oxygen | A broad range of elements and compounds |
Structural units | Ions(positive and negative ions) | Metal atoms(Kernels in sea of electron) | Molecules | Atoms | Covalently bonded networks of atoms or collections of large molecules with short-range order |
Forces holding units together | Ionic bonding | Metallic bonding | London forces, dipole-dipole interactions, hydrogen bonds | Covalent bonds | Covalent bonds |
Typical properties | Hard and brittle, high melting point, poor conductor in solid state but good conductor in molten state, poor thermal conductor | Malleable and ductile, good electrical and thermal conductor, wide range of hardness and melting point | Low to moderately high melting point and boiling point, soft, poor thermal and electrical conductor | Wide range of hardness and melting point, poor thermal and electrical conductor | Non crystalline, high melting point, poor electrical conductor |
Examples | Iron, silver, copper, nickel | Graphite, diamond, quartz, mica | Glass, nylon, polyethylene |
