OXIDATION STATES (OXIDATION NUMBERS) - chemguide
...That would give an oxidation state of -1. You can ignore these if you are doing chemistry at A level or its equivalent. The generalisation that Group 1 metals always have an oxidation state of +1 holds good for all the compounds you are likely to meet. If you are interested in these odd compounds, do an internet search for alkalides....

...Assigning oxidation states: On simple ions, the oxidation state is the charge on the ion e.g. Cu2+ (Cu +2); Cl? (Cl ?1); Al2O3 (Al +3, O -2) In elements, the oxidation state is always zero e.g. Cl2 (Cl 0) The total of all the oxidation states must always equal the overall charge on the species....

oxidation numbers
...Answer: The oxidation state (or oxidation number) is the charge that an atom would have if all bonds were ionic and electrons were transferred completely. For example, in NaCl, sodium has an oxidation state of +1 and chlorine has an oxidation state of-1....

introducing transition metals - chemguide
...Variable oxidation state (number) One of the key features of transition metal chemistry is the wide range of oxidation states (oxidation numbers) that the metals can show. Note: If you aren't sure about oxidation states, you really need to follow this link before you go on. Use the BACK button on your browser to return quickly to this page....

Redox Reaction | A-Level Chemistry Revision Notes
...Redox reaction is divided into two parts. One is oxidation half while the other is reduction half. In oxidation half-reaction, an atom loses electrons, so its oxidation number increases, while in reduction half, an atom or ion accepts electrons, so its oxidation number decreases. Why are redox reactions important?...

Transition Pack for A Level Chemistry - St Paul's Catholic ...
...At A level we use the idea of oxidation number a lot! You know that the metals in group 1 react to form ions that are +1, i.e. Na+ and that group 7, the halogens, form -1 ions, i.e. Br-. We say that sodium, when it has reacted has an oxidation number of +1 and that bromide has an oxidation number of -1....
