Chemistry - Structure and bonding

are metallic solids malleable

yes, it is held together by a non directional “sea” of delocalised electrons so atoms slide over eachother without bonds breaking

are ionic solids malleable

no. it is held together by positively and negatively charged ions in a rigid crystal lattice structure. when force is applied, ions with the same charges line up next to eachother and shatters the crystal as like charges repel each other.

are molecular solids malleable

no. they are held together by weak intermolecular forces, meaning they are typically brittle and soft.

are covalent networks malleable

no. they are held together in a rigid 3d network by strong covalent bonds, meaning they cant bend or slide. they are very hard and brittle.

can metallic solids conduct electricity

yes, both solid and liquid. metals are held in a “sea” of delocalised electrons that can move freely and carry and electrical current.

can ionic solids conduct electricity

only when molten or dissolved in water. when solid, ions are locked in rigid crystal lattice and unable to move. when liquid, ions break free and can move to carry charge

can molecular solids conduct electricity

no.
