Assigning Oxidation Numbers
... +3 in all of its compounds. Oxygen’s oxidation number is -2 except when in hydrogen peroxide (H2 O2 ), or a peroxide ion (O2 2− ) where it is -1. 3. Hydrogen’s oxidation number is +1, except for when bonded to metals as the hydride ion forming binary compounds. In LiH, NaH, and CaH2 , the oxidation ...

Introduction to Oxidation Reduction
... The first three reactions show an element, in this case oxygen, converted to the combined form of oxygen in a compound. An element was converted to a compound in the reactions. In the fourth reaction, a compound decomposed into its elements. General statement-the reactions show the disappearance or ...

... Polar covalent bond: the electrons of the bond are not shared equally. Ex: HCl Ionic Bonds: Two atoms are so unequal in their attraction for valence electrons that the more electronegative atom strips an electron completely away from its partner. Ion: a charged atom (or molecule) Cation: a positive ...

Worksheet 1 - Oxidation/Reduction Reactions Oxidation number
... Balancing Redox Reactions Oxidation/Reduction (Redox) reactions can be balanced using the oxidation state changes, as seen in the previous example. However, there is an easier method, which involves breaking a redox reaction into two half- reactions. This is best shown by working an example. Hydrob ...
