5.1 reactivity series Flashcards
What are ores
rocks from which it is economical to extract the metals that they contain, most are chemically bonded to other elements in compounds
what does oxidised mean
have oxygen added,
what has to be done to extract metal from their oxides
metal oxide must be reduced
What is the reactivity series
list of metals in order of their reactivity, with most reactive metals at the top and least at the bottom
how does the reactivity change when going down group 1
it increases
What happens to pottasium, sodium and lithium when it reacts with water (Group 1)
fizzes, gives off hydrogen gas, leaving alkali solution of metal hydroxide
What does calcium do when it reacts with water
fizzes, gives off hydrogen gas, leaving alkali solution of metal hydroxide
what does magnesium do when it reacts with water
very slow reaction
what does aluminium do when it reacts with water
