metals - all you need to know ..
structure :
the structure of metals is a lattice full of positively charged nuclei and delocaslied electrons. The structure is held together by the electrostsic attraction between the positive nuclei and delocalised electrons ( also known as a metallic bond )
- delocalised - not fixed to any one atom,, the electrons are shared throughout
conductivity :
metals are very very good conductors because of the moving electrons, metals can carry an electrical current.
reactions with metals :
- metal + oxygen = metal oxide
- metal + water = metal hydroxide + hydrogen
- metal + acid = salt and hydrogen
reactivity :
the more the reactive metal , the faster and more the reaction will take place.
salt :
one way…
