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…
