Understand that when metals undergo chemical reactions with other substances, they tend to form positive ions.
Relate the comparative reactivity of a metal to its inherent tendency to form positive ions.
Arrange potassium, sodium, lithium, calcium, magnesium, zinc, iron, and copper in a formal reactivity series based on their interaction with water and dilute acids.
Understand that the non-metals hydrogen and carbon are commonly included in the reactivity series as comparison points.
Explain the principle that a more reactive metal can physically displace a less reactive metal from an existing compound.
Recall and describe the specific reactions (at room temperature) of key metals with water or dilute acids, and place these metals in order of reactivity based on these properties.
Deduce an order of reactivity for unknown metals based entirely on provided experimental results.
