Recall that the activity series gives us the relative reactivities of metals to oxidation: metals higher in the activity series are more reactive to oxidation and vice-versa.
Oxidation → lose electrons
A metal that is high on the series proceeds in the forward directon and lose electrons, forming metal ions.
Can displace Hydrogen from liquid water, steam, and acids.
Can displace Hydrogen from steam and acids.
Chromium (Cr2+, Cr3+)
Iron (Fe2+, Fe3+)
Can displace Hydrogen from acids.
Arsenic (As3+, As5+)
Copper (Cu+, Cu2+)
Mercury (Hg22+, Hg2+)
Platinum (Pt2+, Pt3+)
Gold (Au+, Au3+)
A metal that is high on the series proceeds in the ________directon and _______ electrons, forming ____________.
A metal that is low on the series proceeds in the ________ direction and _______ electrons, forming ________.
Therefore, a metal that is high on the series is _______ to oxidize, whereas a metal that is low on the series is _______ to oxidize.
