Term | Definition |
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 |
