Oxidation number is the charge or the charge of the hypothetical Atom or ion of an element based on the number of electrons that are, or were, according to the criteria established when the various elements together is a compound that gives an electron. Sections that are negative are electron lekoksidechan and is equal to the number of electrons that get it
.
For example, Zn when a compound is 2 electrons to give Zn2 therefore has 2 lekoksidechan
Na is Na, 1 electron for so lekoksidechan = 1
Al as Al3, electron lekoksidechan with 3 = 3
. Cl-1 Cl an electron is given so there is lekoksidechan =-1
O as O2-get 2 electrons are lekoksidechan =-2
