Oxidation and Reduction Flashcards
1
Q
What is reduction?
A
The gain of electrons by a reactant in any reaction.
2
Q
What is oxidation?
A
The loss of electrons from a reactant in any reaction.
3
Q
What is a redox reaction?
A
When reduction and oxidation occur at the same time.
4
Q
What is an oxidising agent?
A
A substance that accepts electrons.
5
Q
What is a reducing agent?
A
A substance that donates electrons.
6
Q
Why do elements with low electronegativities act as reducing agents?
A
As they form ions by losing electrons.
7
Q
When do elements with high electronegativities act as oxidising agents?
A
When they form ions by gaining electrons.
8
Q

A
In Group 1.
9
Q
