Covalent Network Solids and Metallic Bonding (HSC SSCE Chemistry): Flashcards

Molecular, ionic, covalent network, metallic

Covalent bonds extend continuously throughout crystal structure

Covalent lattices

Four

Extremely high, typically above $1000^\circ\text{C}$

No free electrons to move through structure

Positive ions with mobile sea of delocalised electrons

Delocalised electrons move freely through lattice

Ability to be hammered or rolled into thin sheets

Ability to be drawn into wires
