- BONDING
- IONIC
- Metals lose electrons. Non metals gain.
- High melting points
- Ions are free to move when molten so they carry electric current
- Strong electrostatic forces of attraction
- METTALIC
- Free electrons
- conduct heat + electricity
- hold the atoms together in a regular structure
- Strong electrostatic forces of attraction
- Allow layers to slide over each other so the metal can be bent
- Alloys
- Different sized atoms so the layers are distorted and they can't slide over each other
- Free electrons
- COVALENT
- GIANT COVALENT
- Very high melting + boiling points
- Don't conduct electricity
- Graphite - 3 covalent bonds, slide over each other, pencil lead
- Silica - Sand, each grain is a giant structure of silicon and oxygen
- Diamond - 4 covalent bonds, rigid, hardest natural substance, drill tips
- Silica - Sand, each grain is a giant structure of silicon and oxygen
- Graphite - 3 covalent bonds, slide over each other, pencil lead
- Don't conduct electricity
- Very high melting + boiling points
- SIMPLE MOLECULAR
- Weak forces of attraction
- Low melting + boiling points
- Weak forces of attraction
- GIANT COVALENT
- IONIC
- Most are gases and liquids at room temp
- Low melting + boiling points
- Don't conduct electricity because there are no ions
- Silica - Sand, each grain is a giant structure of silicon and oxygen
- Diamond - 4 covalent bonds, rigid, hardest natural substance, drill tips
