| Question | Answer |
| What type of solid consists of metals and non metals | ionic solids |
| carbon and silicon containing compounds sometimes form which type of solid? | extended covalent networks |
| metallic solids are made up of which type of atoms? | metals |
| name the particles involved in metallic solids molecular solids ionic solids extended covalent network solids | the particles involved in metallic solids - atoms molecular solids - molecules ionic solids - ions extended covalent network solids - atoms |
| name the forces between neighbouring particles in metallic solids molecular solids ionic solids extended covalent network solids | the forces involved in metallic solids - metallic bonds molecular solids - weak intermolecular forces ionic solids - ionic bonds extended covalent network solids - covalent bonds |
| why is this solid brittle | this is an ionic solid. when force is applied, like charges align and repel shattering the crystal |
| what types of solids can conduct electricity? | metals graphite (ionic substances only as liquids or in solution NOT as a solid) |
| what types of solids are malleable? | ones with nondirectional forces (metals) |
| describe the structure of metals | metals have atoms surrounded by delocalised valence electrons with non directional metallic bonds connecting these particles |
| describe the structure of ionic solids | an ionic solid is made up of anions surrounded by cations and vice versa. there is a strong electrostatic attraction called ionic bonds between oppositely charged ions |
| describe the structure of diamond | Diamond is a 3D extended covalent network made up of only C atoms. Each C is bonded to 4 other carbons in a tetrahedral arrangement |
| name the solid which has this structure | graphite |
| explain why graphite conducts electricity | each C in graphite has one delocalised electron that exists between the layers. These electrons can carry charge. |
