Question
In a reaction, copper is reduced; its number of electrons has:
- Increased
- Decreased
- Remained Constant
- Varies Randomly
Hint:
Oxidation state is lowered and the number of electrons has increased
The correct answer is: Increased
Reduction is the transfer of electrons between species in a chemical reaction where there is a process of gaining electrons or a decrease in the oxidation state by an element. A reduction chemical reaction involves increasing electrons associated with a single atom or a group of atoms.
In a reaction, copper is reduced; its number of electrons has increases.
