There's Hydrogen and Helium
Then Lithium, Beryllium
Boron, Carbon everywhere
Nitrogen all through the air
With Oxygen so you can breathe
And Fluorine for your pretty teeth
Neon to light up the signs
Sodium for salty times
Magnesium, Aluminium, Silicon
Phosphorus, then Sulfur, Chlorine and Argon
Potassium, and Calcium so you'll grow strong
Scandium, Titanium, Vanadium and Chromium and Manganese
This is the Periodic Table
Noble gas is stable
Halogens and Alkali react agressively
Each period will see new outer shells
While electrons are added moving to the right
Iron is the 26th
Then Cobalt, Nickel coins you get
Copper, Zinc and Gallium
Germanium and Arsenic
Selenium and Bromine film
While Krypton helps light up your room
Rubidium and Strontium then Yttrium, Zirconium
Niobium, Molybdenum, Technetium
Ruthenium, Rhodium, Palladium
Silver-ware then Cadmium and Indium
Tin-cans, Antimony then Tellurium and Iodine and Xenon and then Caesium and...
Barium is 56 and this is where the table splits
Where Lanthanides have just begun
Lanthanum, Cerium and Praseodymium
Neodymium's next too
Promethium, then 62's
Samarium, Europium, Gadolinium and Terbium
Dysprosium, Holmium, Erbium, Thulium
Hafnium, Tantalum, Tungsten then we're on to
Rhenium, Osmium and Iridium
Platinum, Gold to make you rich till you grow old
Mercury to tell you when it's really cold
Thallium and Lead then Bismuth for your tummy
Polonium, Astatine would not be yummy
Radon, Francium will last a little time
Radium then Actinides at 89
Actinium, Thorium, Protactinium
Uranium, Neptunium, Plutonium
Americium, Curium, Berkelium
Californium, Einsteinium, Fermium
Mendelevium, Nobelium, Lawrencium
Rutherfordium, Dubnium, Seaborgium
Bohrium, Hassium then Meitnerium
Darmstadtium, Roentgenium, Copernicium
Tennessine and Oganesson
And then we're done!!
We'll learn how to determine the oxidation numbers or oxidation states for a the elements in a chemical compound. The oxidation numbers tell us how electrons are divided up or shared between atoms in a chemical compound. The oxidation numbers also tell us how electrons move in an oxidation reduction (redox) reaction. There are a set a rules that we use to determine oxidation number. Group 1A elements (alkalai metals) always have an oxidation of +1. Group 2A elements (alkaline earth metals) always have an oxidation number of +2. Elements on their own have an oxidation number of 0, and monatomic ions have an oxidation number that is equal to the ionic charge.

This video is about the different ways that scientists have pictured the atoms over the years. It starts with Democritus and Leucippus, the first philosophers to discuss atoms. Then John Dalton did experiments on atomic theory. J.J. Thompson proposed the plum pudding model of the atom when he discovered electrons, and Ernest Rutherford countered with the nuclear atom when he discovered the nucleus in the gold foil experiment. Niels Bohr imagined that electrons circled the nucleus in orbits, and Erwin Schrodinger's quantum mechanical model pictures electrons buzzing around in orbitals.
I made this during the leaving for fun. I got an A+ in chemistry. Do remember that this was made for myself to learn, it could contain a few spelling mistakes or other issues. If you do like the way it's written and helps you understand, I could post a few more of my notes in here.
