Study Notes
Reactivity Series
- A list of metals in order of their reactivity, with the most reactive at the top and the least reactive at the bottom
- The series is based on the metal's ability to lose electrons and form ions
- The reactivity series consists of, in order: potassium (K), sodium (Na), calcium (Ca), magnesium (Mg), aluminium (Al), zinc (Zn), iron (Fe), tin (Sn), lead (Pb), copper (Cu), silver (Ag), and gold (Au)
Oxidation States
- The oxidation state of an element is the number of electrons it has lost or gained to form a bond
- Metals tend to lose electrons to form a positive ion (cation) and have a positive oxidation state
- The oxidation state of a metal can vary depending on the reaction it is involved in
- Examples of oxidation states include:
- Sodium (Na) typically having an oxidation state of +1
- Iron (Fe) having oxidation states of +2 or +3
- Copper (Cu) having oxidation states of +1 or +2
Metal Displacement
- A reaction in which a more reactive metal displaces a less reactive metal from its compound
- The more reactive metal loses electrons and becomes an ion, while the less reactive metal gains electrons and becomes a neutral atom
- The reactivity series can be used to predict the outcome of metal displacement reactions
- Examples of metal displacement reactions include:
- Zinc (Zn) displacing copper (Cu) from copper(II) sulfate solution
- Iron (Fe) not displacing copper (Cu) from copper(II) sulfate solution because iron is less reactive than copper
