C1-Atomic structure and the periodic table

• Group 1 element trends (as you go down the group)


  -Reactivity increases (outer electron is further away from nucleus, more easily lost)

  -Decreasing boiling and melting point
• How are alkali metals usually stored and handled?


  Stored in oil ,handled with forceps (because they are incredibly reactive)
• Group 0 element trends (as you go down the group)


  -Higher melting and boiling points (increasing atoms ,increasing intermolecular forces so takes more energy to break.)

  -Reactivity does not change as they are all stable
• Group 7 element trends (as you go down the group)


  -Become less reactive (harder to gain an electron)

  -Increasing melting and boiling points

  -Denser states (going from gases to solids)
• What can happen if two halogens are put into a creation together?


  If one halogen is more reactive than the other ,it can displace the halogen (in a compound).
• What colour gas is fluorine typically?


  yellow
• What colour gas is chlorine typically?


  green
• What colour liquid is bromine typically?


  Red/brown
• What colour gas/solid is iodine typically?


  Purple vapour or grey crystalline solid
• What is the product of an alkali metal and chlorine reacting?


  Metal chloride salt (ionic compound)
• What is the product of an alkali metal and water reacting?


  Metal hydroxide and hydrogen
• What is the product of an alkali metal and oxygen reacting?


  Metal oxide
• In what instance can simple distillation not be used to separate a mixture of liquids?


  If the boiling points of the liquids are too similar
• What is the equipment used for filtration?


  -Funnel

  -Beaker
