13) REDOX Flashcards
What is oxidation
The loss of electrons
What is reduction
Gain of electrons
What is a redox reaction
Where both oxidation and reduction take place at the same, simultaneously
What is a reducing agent
Substance that donates electrons, causing reduction, but undergoes oxidation itself
What elements are good reducing agents and why
Give an example
Elements with low electronegativities
Why? Because they can hold onto electrons well
Examples:
Alkali metals
What elements are good oxidising agents and why
Give an example
Elements with high electronegativities
Why? Because they attract electrons more strongly
Examples:
Halogens
What is an oxidising agent
Substances which takes away electrons causing oxidation, but undergoes reduction itself
Elements at the top right of the EC series are strong…
