  • Redox Reaction
    A process where one element is removed from a compound by another, involving electron transfer and changes in oxidation states.
  • Displacement
    The removal of an element from its compound by another, resulting in the reduction of the displaced element.
  • Activity Series
    A ranked list of elements showing their ability to displace others, predicting which reactions will occur spontaneously.
  • Reducing Agent
    A substance with a strong tendency to lose electrons, causing another to gain electrons and be reduced.
  • Oxidizing Agent
    A substance with a strong tendency to gain electrons, causing another to lose electrons and be oxidized.
  • Oxidation
    A process involving the loss of electrons, typically occurring in elements higher on the activity series.
  • Reduction
    A process involving the gain of electrons, typically occurring in elements lower on the activity series.
  • Electron Transfer
    The movement of electrons from one element to another, driving the changes in redox reactions.
  • Spontaneity
    The natural tendency of a reaction to occur without external input, as predicted by the activity series.
  • Oxidation State
    A value representing the number of electrons lost or gained by an atom in a compound during a reaction.
  • Tendency to Lose Electrons
    A characteristic of elements higher in the activity series, indicating a strong likelihood of undergoing oxidation.
  • Tendency to Gain Electrons
    A characteristic of elements lower in the activity series, indicating a strong likelihood of undergoing reduction.
  • Compound
    A chemical substance formed from two or more elements, which can be broken apart during displacement.
  • Element
    A pure substance that can participate in redox reactions, either displacing or being displaced in compounds.
