Element Groups Flashcards
What group number, ion charge and metal/non metal are alkali metals?
group 1, metal, +1
What group number, ion charge and metal/non metal are alkali earth metals?
group 2, metals, +2
What group number, ion charge and metal/non metal are transition metals?
groups 3-12, metal, usualy 2+ can be 1+ 3+ 4+
What group number, ion charge and metal/non metal are halogens?
group 17, non metal, -1
What group number, ion charge and metal/non metal are noble gasses?
group 18, non metal, non reactive
What group number, ion charge and metal/non metal are Lanthanides?
groups 57-71, metals, non reactive
What group number, ion charge and metal/non metal are actinides?
groups 89-103, man made non- metals, non reactive
Name 2 chemical properties of alkali metals?
very reactive
violently reactive with water producing alkaline/basic solution and hydrogen gas
Name 2 chemical properties of alkali earth metals?
(SAME AS ALKALI METALS)
slightly less reactive
violently reactive with water producing alkaline/basic solution and hydrogen gas
Name 2 chemical properties of transition metals?
have various oxidation states
form colour compounds
Name 2 chemical properties of halogens?
get bigger/less reactive as you move down group
form colour compounds
Name 2 chemical properties of noble gases?
very stable/only react under extreme circumstances
get less dense as you move down from group 18
Name 2 chemical properties of lanthanides?
contain at least one stable isotope
very reactive with elements from halogen group
Name 2 chemical properties of actinides?
very reactive with halogen group
radio active
Name 3 physical properties of alkali metals
found as compounds because are too reactive to be naturally pure
silvery,shiny
