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))

[sciencesolutions]

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.

made a neodymium isotope because i felt like it :>

awww what a sweetheart :3

I think it's worth mentioning that (as far as we know) she's the second-most-stable radioisotope of Neodymium, with a half-life of 2.3 quadrillion years, surpassed only by Nd-150's 9.3 quintillion years, and is also the second most abundant isotope after baseline Neodymium (Nd-142)! 24% of neodymium cattos on Earth would be these

drew my two favorite cattos

i do not know why i gave silicon a tie

Omg the beans :333 Sil is rocking that tie ngl makes him look like a proper office guy lol

Europium!

New design courtesy of @ichibin-irish, @velcrow101, @sciphonpylon and me

Largely based on europium's use in CRT televisions, particularly in emitting red light. The hair is based on this. The europlug and RCA cables are just TV-related things.

Version without glasses. look at this thing

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.
