The Periodic Table Flashcards
What are Group 1 metals called?
Alkali Metals
What are Group 2 metals called?
Alkali Earth Metals
what are group 18(8) called?
Noble gases
What happens to metals eg:Group 1 and Group 2 as they go down the group?
The elements become more reactive
What happens to non metals eg: Group 6 and Group 7 as they go down the group?
Elements become less reactive
Group 1 metal: Lithium and cold Water reaction what can be seen?
slow reaction - floats doesn’t melt
slowly dissolves to produce an alkaline solution of LiOH
h2 gas given off and burns with a crimson red flame when ignited
Group 1 metal: Sodium and cold Water reaction what can be seen?
reacts more strongly than Li
moves around the surface and dissolves quickly to form alkaline NaOH
h2 gas given off and when ignited yellow-orange flame
Group 1 metal: Potassium and Water reaction what can be seen?
reacts vigorously
moves rapidly on surface
quickly dissolves - produces alkaline solution of KOH
h2 gas given off and when ignitked ti produces a lilac flame
What happens when you add more reactants?
equm moves to right to remove the added reactants
what happens when you remove some of the reactants?
equm moves to left to replace some of the reactants
What happens if you add more products?
equm moves left to remove some of the products
what happesn if you remove some products?
equm moves right to replace products
what happens to equm when temp is increased?
moves in the endothermic direction to lower temp
what happens if temp is decreased?
moves in the exothermic direction to increase temp
what happens to equm if pressure is decreased?
moves to side where there is more number of moles
