reaction of metals Flashcards
what are oxidation reactions?
Metals reacting with oxygen to produce metal oxides.
what happens when metals react?
they lose electrons to form positive ions
what is the reactivity series?
potassium, sodium, lithium, calcium, magnesium, aluminium, (carbon) zinc, iron, tin, lead, (hydrogen), copper, silver, gold.
what can a more reactive metal do?
displace a less reactive metal from a compound.
what happens with metals more reactive than hydrogen?
will react with acid and produce hydrogen gas.
Hydrogen gas ‘pops’ with a lighted spill.
how can metals less reactive than carbon can be extracted from their ores?
by reduction with
carbon.
what does reduction involve the loss of?
the loss of oxygen.
what is reduction?
the gain of electron.
what is oxidation?
the loss of electrons.
