OXIDATION

Oxidation number

Is a number assigned to an atom in a substance that represents the atoms apparent change based on the assumption that all binding electrons belong to the more electronegative atom

Oxidation state

Oxidation number is also known as

Oxidation number

Useful for tracking movement of electrons during chemical reactions

+ 1 + -1 = 0

Na = + 1 Cl = -1

Zero

Free elements have an oxidation number of

The sum of all oxidation numbers for the atoms in a neutral molecule or compound is

Al(oh)3

Give me an example of neutral compound

Overall charge of that ion

The sum of all oxidation numbers for the atoms in a polyatomic ion equals to the

CO3²‐ SO4 ²‐

Give me the two examples in the powerpoint of polyatomic ion

CO3²- = -2 SO4²- = -2

How do you write the rule number 8 polyatomic ion with CO3²- & SO4²-
