The lich / l ɪ tʃ / [1] is an undead creature found in the Dungeons & Dragons (D&D) fantasy role-playing game. Liches are spellcasters [ 2 ] who seek to defy death by magical means. The term derives from lich , an archaic term for a corpse .
Arthas Menethil is a fictional character who appears in the Warcraft series of video games and novels by Blizzard Entertainment.He was once a paladin of the Silver Hand and the crown prince of Lordaeron, but he was corrupted by the cursed blade Frostmourne in a bid to save his people.
[12] In the webcomic The Order of the Stick, the main villain Xykon is a lich. [13] In the Harry Potter series, the main antagonist Voldemort commands armies of undead inferi and uses magical devices called horcruxes to store fragments of his soul in order to allow him to resurrect himself in the event that his body dies.

Thorium forms the monocapped trigonal prismatic anion [Th(CH 3) 7] 3−, heptamethylthorate(IV), which forms the salt [Li(tmeda)] 3 [Th(CH 3) 7] (tmeda = (CH 3) 2 NCH 2 CH 2 N(CH 3) 2). Although one methyl group is only attached to the thorium atom (Th–C distance 257.1 pm) and the other six connect the lithium and thorium atoms (Th–C ...
English: Diagram of the thorium decay chain from lead-212 to lead-208. Each parent nuclide spontaneously decays into a daughter nuclide (the decay product) via an α decay or a β − decay. Note that bismuth-212 can either decay into polonium-212 or thallium-208.
Monazite contains 2.5% thorium, allanite has 0.1 to 2% thorium and zircon can have up to 0.4% thorium. [2] Thorium-containing minerals occur on all continents. [ 3 ] [ 4 ] [ 5 ] Thorium is several times more abundant in Earth's crust than all isotopes of uranium combined and thorium-232 is several hundred times more abundant than uranium-235.
Thorite, (Th,U)SiO 4, is a rare nesosilicate of thorium that crystallizes in the tetragonal system and is isomorphous with zircon and hafnon. It is the most common mineral of thorium and is nearly always strongly radioactive. Thorite was discovered in 1828 on the island of Løvøya, Norway, by the vicar and mineralogist, Hans Morten Thrane Esmark.
Although thorium-232 mainly decays by alpha decay, it also undergoes spontaneous fission 1.1 × 10 −9 % of the time. [3] In addition, it is capable of cluster decay , splitting into ytterbium-182 , neon-24 , and neon-26 ; the upper limit for the branching ratio of this decay mode is 2.78 × 10 −10 %.
