  • Group 1 (Alkali Metals)
    • Sodium (Na)
    • Lithium (Li)
    • Potassium (K)
    • Rubidum (Rb)
    • Caesium (Cs)
    • Francium (Fr)
    • Physical Properties & Facts
      • Highly Reactive
        • Reactivity increases down Group 1
        • They need to be stored in oil to avoid vigorous reactions with
          • Oxygen
            • Oxides
            • Peroxides
            • Superoxides
          • Halogens
            • Ionic Salts
      • Low density
      • Silvery Colour
      • Soft texture
      • Low melting and boiling point
        • They decrease down Group 1
          • Atomic size increase down the group
        • Larger atomic radius
          • Weak Metallic Bonds
            • Delocalised electrons further away from the nucleus
            • Only have one electron to contribute to the 'sea' of delocalised electrons
  • The outermost valence electron is more likely to be removed
    • Electron donors (during reactions)
      • Cations
    • Low ionisation energy
      • Highly Reactive
        • Reactivity increases down Group 1
        • They need to be stored in oil to avoid vigorous reactions with
          • Oxygen
            • Oxides
            • Peroxides
            • Superoxides
          • Halogens
            • Ionic Salts
  • Great distance between neighboring atoms in a metallic lattice
    • Lower termal energy needed to separate the atoms
    • Atomic size increase down the group
