oxidation-reduction reactions redox reactions
chemical reaction where electrons are transferred from one reactant to another TERM 2
half-reaction
DEFINITION 2 the oxidation or the reduction reaction in the redox reactionthe sum of the two half-reaction equations is the overall equation for the redox reaction TERM 3
oxidation
DEFINITION 3 the lossof electrons TERM 4
reduction
DEFINITION 4 the gainof electrons TERM 5
reducing agent
DEFINITION 5 a species that donates its electrons
oxidizing agent
a species that accepts electrons TERM 7
oxidation number oxidation
state
DEFINITION 7 the charge an atom would have ifelectrons were transferred completely elements that show an increasein oxidation number are oxidized elements that show a decreasein oxidation number are reduced for polyatomic ions, oxidation numbers must sum to the charge on the ion TERM 8
displacement reaction
DEFINITION 8 reaction in which two reactants trade components (double displacement) or where a component of a reactant is removed (single displacement) TERM 9
activity series
DEFINITION 9 List of metals (and hydrogen) arranged from top to bottom in order of decreasing ease of oxidation(Table 4.5) an element in the series will be oxidized by the ions of any element that appears below it TERM 10
active metals
DEFINITION 10 metals lists at the top of the activity series include the alkali and alkali earth metals these metals are so reactive that they are not found in nature in their elemental forms
combustion reaction
reaction in which two or more reactants combine to form a single product
