Reaction of metals Flashcards
(12 cards)
What do metals produce when they react with oxygen?
Metal oxides
What are metals reacting with oxygen reactions called?
Oxidation reactions
What do metals lose when they react?
Electrons to form positive ions
What is the reactivity series?
Places metals in order of reactivity
From most to least, what makes up the reactivity series?
Potassium, sodium, lithium, calcium, magnesium, aluminium, (carbon), zinc, iron, tin, lead, hydrogen, copper, silver, gold
What does a more reactive metal do?
Displaces a less reactive metal from a compound
What do metals more reactive than hydrogen react with?
React with acid and produce hydrogen gas
What does hydrogen do with a lit splint?
Hydrogen gas ‘pops’ with a lit splint
How can metals less reactive than carbon be extracted?
By reduction with carbon
What does reduction involve?
The loss of oxygen
What is reduction?
The gain of electrons
What is oxidation?
The loss of electrons
