  • Metals on the left and non-metals on the right,
  • Group 1 are the Alkali metals and all react with water to form alkaline solution and hydrogen.
  • Group 7 are the Halogens which form salts when they react with metals.

Group 1 Metals- The Alkali Metals

  • Reactivity increases
  • Density increases
  • Melting point decreases
  • Boiling point decreases
  • With water they produce a HYDROGEN…
