What is oxidation?
The process of electron loss
What is an oxidising agent?
An electron acceptor
What is reduction?
The process of electron gain
What is a reducing agent?
An electron donor
What is disproportionation?
The same species is both oxidised and reduced
What is oxidation state?
Charge on the ion or atom
Where is the overall oxidation state found?
The top right
What are the rules for assigning oxidation states?
in a compound, the more electronegative element is given the more -ve oxidation number
fixed oxidation states: group 1= +1, group 2= +2, F= -1
Hydrogen is +1 except in metal hydrides, where it is -1
Oxygen is -2 except in peroxides, where it is -1 and F2O, where it is +2
Chlorine is -1 except with O or F
