Chemistry

• Physical Properties of Alkali EARTH Metals:


  1.) Shiny silvery-white

  2.) Low density, melting, and boiling points
• Chemical Properties of Alkali EARTH Metals:


  1.) LESS reactive than corresponding group 1 elements

  2.) Alkaline/ basic/ pH <7
• Physical Properties of Halogens:


  1.) Melting and boiling points INCREASE DOWN the group
• Chemical Properties of Halogens:


  1.) LESS reactive as you go DOWN in group

  2.) Coloured and poisonous vapours
• Physical Properties of Nobel Gases:


  1.) Very low boiling points
