i wonder if uranium gets something for being the heaviest naturally occurring element (i have decided to not include plutonium bc it basically isnt there) (and yes im calling uranium fat /j))

For uranocene, the correct statement(s) is/are:

(A) Oxidation state of uranium is ‘+4’. (B) it has cyclooctatetraenide ligands (C) it is a bent sandwich compound (D) it has ‘+2’ charge.

Correct answer is

1. A and B

2. B and C

3. A and D

4. B only

Plutonium!

An updated design courtesy of @sciphonpylon, with some more references to the element's namesake and a slightly more plutonian overall colour.

Though a primordial element and not a man-made one, Plutonium was discovered through synthesis in 1940-1941. Since this was the next element after Uranium and Neptunium, he was named after what was then considered the next planet, Pluto. Interestingly, some of his discoverers considered the names "Ultimium" and "Extremium" since they believed they had found the last element on the periodic table. In a way they were right - this is the last known naturally occurring element.

Plutonium is produced very rarely in nature, when Uranium undergoes neutron capture. Predictions suggest that there could still be tiny quantities of this most stable isotope, Plutonium-244, left over from Earth's formation, making Plutonium the heaviest primordial element, but this has yet to be proven.

Dubnium & Californium

Dubnium designed by @thecheese85 and @ichibin-irish, Californium by Whail/Lfyz, @ichibin-irish, @thatmarkerdude, @haniszar36, @lythic-felinementals and @a-thalassophiliac (aka @autism-detector), both with a few additions and alterations by me

Being extremely unstable synthetic elements that not much is known about, their designs are largely based on their namesakes - the Russian city of Dubna (where the JINR is located) and both the university and state of California.

Californium is sometimes used in portable metal detectors, being a very strong neutron emitter.

Lanthanum, Actinium & Dysprosium redesigns

Actinium is courtesy of @ichibin-irish, the rest are by me with help from @sciphonpylon

Lanthanum's design has many more of the element's applications incorporated in it. His eyes are now lights as well, and he wears glasses since lanthanum compounds - particularly lanthanum(III) oxide - are used as additives in glass (though not in actual glasses but yknow, cute). His tail is a welding electrode, his body is a scintillation crystal/detector, and between his ears is a LaB6 cathode.

Actinium's design is mainly based on this particular isotope's potential use for radioisotope thermoelectric generators in things such as spacecraft. His backpack is such a generator according to Irish.

Dysprosium has a laser pointer tail, a hard drive on her back, wind turbines on her ears and a dosimeter in her forehead. Her blush and tongue are a bright green in reference to dysprosium oxide, though more saturated for the sake of looking nicer.

Also Rhodium has a catalytic converter tail now!
