Oxidations, by Vera Lenhdorff and Holger Trülzsch.
Oxidation Numbers
Definition: The measure of the number of electrons involved in the bonding of a compound.
Oxidation: The loss of electrons
Reduction: The gain of electrons
The Rules
Metals are positive, non-metals are negative in a compound with only 2 elements.
The sum of the oxidation numbers in a compound must be 0.
the oxidation number of a standalone element is also 0
The oxidation number of a standalone ion is equal to its charge
The sum of Oxidation numbers in an ion with more than one element is equal to the charge on the ion.
Some elements have variable oxidation numbers : Hydrogen = +1, Oxygen = -2 , Fluorine = -1
Atoms that have been oxidized will have increased in oxidation number because it gains more protons
Atoms that have been reduced will have decreased in oxidation number because it gains more electrons
Oxidizing Copper
This is a photo of a copper firepit weeks after it was exposed to the elements. Oxidations has begun and creating a wonderful iridescent patina that when photographed translated into a beautifully rich color field.
