Oxidation number is the hypothetical charge or fee charge of an atom or ion of the elements by a number of electrons that give or receive, based on the criteria that determine when the various elements together is a compound chemical that allows electrons to have a positive and lekoksidechan is equal to the number of electrons that make it. The part that the electron will have received negative and lekoksidechan is equal to the number of electrons that get it.For example, when a compound is Zn, Zn2 + 2 electrons is therefore has lekoksidechan + 2. Na is Na +, the electron is lekoksidechan = 1 + 1. Al3 +, Al is the electron is lekoksidechan = 3 + 3. Cl-1 Cl is the electron a has lekoksidechan =-1. O as O2-2 electron is lekoksidechan =-2.
