Lesson Details
Key learning points
- A more reactive element will replace a less reactive element in a compound (displacement).
- The more easily a metal atom forms a positive ion, the more reactive it is.
- Some metals react with acid to produce a metal salt and hydrogen gas.
- Some metals react with water to produce a metal hydroxide and hydrogen gas.
- Carbon is a non-metal element often included in the reactivity series between aluminium and zinc.
Common misconception
Thinking that a metal and acid react together to produce salt and water.
Use symbol equations to show how hydrogen is produced, rather than water, due to the absence of oxygen atoms.
Keywords
Ion - An ion is an atom or group of atoms with a positive or negative charge due to the loss or gain of electrons.
Salt - A salt is an ionic compound formed from positive and negative ions electrostatically attracted to each other.
Reactivity series - The reactivity series shows metals placed in order of reactivity with the most reactive metal at the top.
Displacement - Displacement is where a more reactive element takes the place of a less reactive element in a compound.
