Types of Solids

Question 1

Metallic

Answer 1

• Metallic Bonding
• Variable hardness, variable melting point (MP), conducive
• Ex: Fe, Mg

Question 2

Ionic

Answer 2

• Ionic Bonding
• hard, high melting point (MP), brittle, NON-conducive
• Ex: NaCl, MgO

Question 3

Covalent Network

Answer 3

• Network of covalent bonds
• Hard, high melting point (MP), NON-conducive
• Ex: C (diamond, graphite), SiO2 (quartz)

Question 4

Molecular (IM forces)

Answer 4

• IM forces
• Soft, low melting point (MP), non-conducive
• Ex: H2O, CO2
