Answers
Answer:
Red-ox reactions
Red-ox is short for oxidation reduction reaction. The two always go together. It is not possible to have a reduction reaction without an oxidation reaction.
A red-ox reaction is a reaction in which the oxidation states of some of the atoms change.
Oxidation number is a formalized way of keeping track of oxidation state.
When molecules and ionic compounds form electrons are rarely shared equally.
e.g. CF4 is held together by covalent bonds. Even though the electrons are shared, the electrons are not shared equally. Fluorine attracts electrons more strongly than Carbon, so the electrons spend more time near the Fluorine. Chemists have invented an accounting method to keep track of the electrons.
The atom that more strongly attracts the electron is "given " the electron.
in CF4 the oxidation number of the
C is +4
