Protactinium 91 (Pa) - The very long half life of the most common isotope makes protactinium suitable for radio dating deep ocean sediment.
vs
Radium 88 (Rd) - If you're on tumblr you've seen the posts about the radium girls. The ones who painted the watch dials for the glow in the dark watches.

ACTNOIDS: ROUND 1 POLL 1
Tumblr media Tumblr media
THORIUM:
used to make ceramics, welding rods, camera and telescope lenses, fire brick, heat resistant paint and metals used in the aerospace industry, as well as in nuclear reactions
Named after the greek god thor
PROTACTINIUM:
exists as a mono-oxo ion instead of a di-oxo ion (which is what actnoids usually exist as)

Calcite contains uranium-234 atoms, which decay with a half-life of 245,000 years into thorium-230, which in turn decays with a half-life of 75,000 years.

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
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 aggressively
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
Molybdenum, Technetium
(Ruthenium) Rhodium, Palladium
(Silver-war) 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 to
Promethium, then 62's
Samarium, Europium, Gadolinium and Terbium
Dysprosium, Holmium, Erbium, Thulium
Ytterbium, Lutetium
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
This is the Periodic Table
Noble gas is stable
Halogens and Alkali react aggressively
Each period will see new outer shells
While electrons are to the right
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
Nihonium, Flerovium
Moscovium, Livermorium
Tennessine and Oganesson
And then we're done
Wonderful job

THE IDEA
There are 118 elements in the periodic table. The elements are as follows:
Hydrogen, Helium, Lithium, Beryllium, Boron, Carbon, Nitrogen, Oxygen, Fluorine, Neon, Sodium, Magnesium, Aluminium, Silicon, Phosphorus, Sulfur, Chlorine, Argon, Potassium, Calcium, Scandium, Titanium, Vanadium, Chromium, Manganese, Iron, Cobalt, Nickel, Copper, Zinc, Gallium, Germanium, Arsenic, Selenium, Bromine, Krypton, Rubidium, Strontium, Yttrium, Zirconium, Niobium, Molybdenum, Technetium, Ruthenium, Rhodium, Palladium, Silver, Cadmium, Indium, Tin, Antimony, Tellurium, Iodine, Xenon, Caesium, Barium, Lanthanum, Cerium, Praseodymium, Neodymium, Promethium, Samarium, Europium, Gadolinium, Terbium, Dysprosium, Holmium, Erbium, Thulium, Ytterbium, Lutetium, Hafnium, Tantalum, Tungsten, Rhenium, Osmium, Iridium, Platinum, Gold, Mercury, Thallium, Lead, Bismuth, Polonium, Astatine, Radon, Francium, Radium, Actinium, Thorium, Protactinium, Uranium, Neptunium, Plutonium, Americium, Curium, Berkelium, Californium, Einsteinium, Fermium, Mendelevium, Nobelium, Lawrencium, Rutherfordium, Dubnium, Seaborgium, Bohrium, Hassium, Meitnerium, Darmstadtium, Roentgenium, Copernicium, Nihonium, Flerovium, Moscovium, Livermorium, Tennessine, Oganesson
There happen to be 10 categories in the periodic table:
Other nonmetals, Alkali metals, Transition metals, Post-transition metals, Metalloids, Alkaline earth metals, Noble gases, Halogens, Lanthanoids, and Actnoids.
Seeing as there are ten options max in tumblr polls, I have decided to make a tournament for every single element in the periodic table. I will give fun facts about each element when they appear in the tournament. When there are ten options left (one for each category), they will all go against each other in one final poll to determine the best element in the periodic table.
I am not starting right away but I will start eventually.
