1

what is the free element rule?

The oxidation number of atoms in there pure form and atoms in pure element zero.

2

what is the ion rule?

The oxidation number of a manatomic ion is equal to the charge of the ion.

3

What is the zero sum rule?

 I can't bring people back from the dead. It's not a pretty picture. I DON'T LIKE DOING IT! The sum of all the oxidation numbers in a compound must be zero

4

2

Oxygen is normally an oxidation number of _____?

-2 oxidation number

3

How do you find oxidation numbers?

Please use the bord to do a criss cross Meathod example for Aluminum and Oxide

Al+3  O2- = Al2O3

please recite the pom catch a little rhyme by eve merriam

Once upon a time
I caught a little rhyme

I set it on the floor
but it ran right out the door

I chased it on my bicycle
but it melted to an icicle

I scooped it up in my hat
but it turned into a cat

I caught it by the tail
but it stretched into a whale

I followed it in a boat
but it changed into a goat

When I fed it tin and paper
it became a tall skyscraper

Then it grew into a kite
and flew far out of sight...
