Metals
- Crystal Structure
- Metallic bonds hold metals together
- Allow outer electrons to move freely
- delocalised (free) electrons
- Melting, Boiling and Density
- Metals are hard
- Strong attraction between delocalised electrons and positive ions
- high melting and boiling points because of the attraction
- Metallic bond decreases the more shells the atom has
- Malleable and Conductors
- Hard to break and strong
- can be made into different shapes
- free electrons carry electricity
- Carry heat energy through the metals
