|---|---|---|---|---|---|
| Physical Properties of Metals | strong, malleable, ductile, sonorous, shiny, good conductors of heat & electricity, high mpts and bpts, high density
🗑
|
||||
| Why are metals strong? | atomic density=stable and close together
🗑
|
||||
| Why are metals malleable? | layers of metal atoms can be shifted without breaking metallic bonds
🗑
|
||||
| Why are metals ductile? | layers of metal atoms can be shifted as well
🗑
|
||||
| Why are metals sonorous? | delocalized electrons sending waves of kinetic energy, little energy lost
🗑
|
||||
| Why are metals shiny? | vibrating delocalized electrons contact with light
🗑
|
||||
| Why are metals good conductors of heat & electricity | delocalized electrons able to carry the energy and the flow of charge
🗑
|
||||
| Why do metals have mpts and bpts? | strong metallic bonds
🗑
|
||||
| Why do metals have high density? | strong metallic bonds with ‘sea’ of delocalized electrons, closely packed
🗑
|

| Chemical Properties of Metals | react with oxygen to form oxides (which are bases) which then form salts and water when reacting with acids & when they react, they form positive ions
🗑
