it has more electrons in the product than in the reactant
If an element has gained electrons, it has been reduced. If an element has lost electrons, it has been oxidized. This can be determined by comparing the oxidation state of the element before and after the reaction.
The reactant that reduces another atom
An element has been reduced if it gains electrons during a chemical reaction, resulting in a decrease in its oxidation state. This can be observed in redox reactions where the element transitions from a higher oxidation state to a lower one. Additionally, you can identify reduction by using oxidation state rules or by observing changes in color or properties in a reaction involving the element.
Sodium (Na) has been reduced.
Silver cations are reduced.
Silver (Ag)
The element has gained one or more electrons....
The element has gained one or more electrons....
Potassium is the element that is most easily reduced because it has a low ionization energy and readily loses an electron to form a +1 cation.
The corrosion on iron can be reduced by suitable thin layer of element to be electroplated.
The element that is most likely to be reduced is the element that has the highest reduction potential (E°) in a given redox reaction. The element with a more positive reduction potential is more likely to undergo reduction.
In the redox reaction, silver (Ag) has been reduced because it gains electrons in forming solid silver (Ag) from silver nitrate (AgNO3).
