Topic 6- Groups in the perioidic table

Question 1

Group 1- Alkali Metals

Answer 1

• Reactive, more reactive down the table as the forces are weaker holding the electrons
• One outer shell electron
• First column of the periodic table
• A reaction would produce a hydroxide and hydrogen gas

Question 2

Group 7 - Halogens

Answer 2

• Reactive, more reactive as you go up the table.
• 7th group in periodic table, 7 electrons in outer shell
• The atomic radius is larger down the table
  Fluorine, Chlorine, Bromine, Iodine and Astatine
  Gas , Green Gas, Brown Liquid, Silver Solid and Black Solid

Question 3

Group 8/0 - Noble Gases

Answer 3

• Full outer shell
• Inert
• Used in filament lamps
• Helium, Neon, Argon, Krypton, Xenon, Radon
• From colourful compounds

Question 4

Reactions of Halogens

Answer 4

• Displacement
• The more reactive halide will replace another
• Zinc Bromide + Chlorine = Zinc Chlorine + Bromine
