List of fictional elements, materials, isotopes and subatomic particles

Columns: Name | Source | Uses
Arsonium | I Expect You to Die | A green liquid with the symbol Ar and the atomic number 7 that makes a compound that is corrosive to copper when mixed with Galine and Sanite , and a compound that produces clouds when exposed to air when mixed with Regalite | Atium | Mistborn book series | A metal that forms the body and power of the shard Ruin . If an Allomancer burns the metal , it allows the user to see a few seconds into the future as a ghostly image overlaid on the present . This allows the user to gain a significant advantage in combat , as it allow them to know every move their opponent will make . This is cancelled out if the opponent burns atium or electrum themselves , as it causes a feedback loop and causes the user to see a mess of possible futures . It is extremely valuable in the Final Empire , as it is both very rare and hoarded by the Lord Ruler . The only place it is found is in the pits of Hathsin , where small nuggets are formed in geodes mined by slaves . Using allomancy near the crystals that form the geodes destroys them . When used by a Feruchemist , it allows them to store age and , if compounded , can result in a complete stop of ageing . Its name comes from the holder of the shard , Ati . in the Wax and Wayne era , no samples exist and it is referred to as 'the lost metal ' . It forms the alloy Malatium , also known as the eleventh metal , a metal that allows the user to see past versions of other people . A misting that burns atium is known as a seer . Hemalurgic effects are unknown | Australium | Team Fortress 2 | An extremely valuable element appearing in Team Fortress 2 by Valve . In-game , it appears as a special type of weapon , and as the fuel for the rocket in the map SD_Doomsday in the Special Delivery game mode . In the bonus comics featured on the Team Fortress website , their role is fleshed out more ; The Life-Extending machines used by The Administrator , Blutarch , Redmond , and Gray Mann are powered by Australium , and a large part of the plot revolves around hiding the vast stores of Australium Their role in the story is that the material , found in Australia , hence the name Australium , makes one smarter over time , but at the cost of increasing 'manliness and beard levels ' in those who use it . As mentioned above , the name comes from the country of Australia and the Neo-Latin '-ium ' used to denote a metallic name . Its appearance is similar to the real-life element gold | Bavarium | Just Cause 3 | Discovered by Medici 's tyrannical ruler Sebastiano Di Ravello in the late 1980s , Bavarium is referred to as a supermineral in reference to its near-infinite potential . Exclusive to Medici , Bavarium is at the core of much of the country 's experimental weaponry and equipment- which , as of the Bavarium Sea Heist DLC , includes gravitational manipulators and personal force fields -as well as a major export ; Di Ravello is able to use it as a bargaining chip when dealing with the Agency . In-game , Bavarium- in its refined form , at least -is shown to be highly volatile and prone to large , violent explosions- a small Bavarium-based charge is capable of instantly destroying all but the largest of the game 's Chaos Objects | Bolognium / Bolonium | Various sources | A metallic element with variable properties ; a substitute for any unspecified substance or element ; or in science fiction writing , a substance or process invented to circumvent explanation or impossibility . A humorous story from 1926 about the development of alloys for special purposes , describes Bolognium as a metallic element with properties similar to Gafnium , with which it forms alloys impervious to attacks by mice . Bolognium may also refer to any unspecified substance or element : if not oil then beryllium , and if not beryllium then bolognium , do n't worry about whether it is mercury or lead or cadmium or 'bolognium ' . Noted science fiction writer David Gerrold attributes the use of the term in science fiction writing to Larry Niven , the author of Ringworld , who used it to describe imaginary materials or processes capable of explaining properties unachievable through known or scientifically-postulated means . In Worlds of Wonder , Gerrold describes two examples from Ringworld : scrith , a substance strong enough to be used for the construction of a ring one hundred and eighty million miles in diameter , and a character deliberately bred for the property of luck . Gerrold refers to bolognium as technobabble , and cautions writers against overusing it , or using it carelessly , as doing so undermines the illusion of reality upon which good science fiction relies . The term itself has appeared in episodes of The Simpsons , in which Bolognium , atomic symbol Bo , appears in the place of Molybdenum , atomic number 42 , on promotional copies of the periodic table produced by Oscar Mayer ( its atomic weight is delicious or snacktacular ) , and in Futurama , where Cubert Farnsworth exclaims , your explanations are pure weapons-grade bolognium ! Although most references to Bolognium are intentionally humorous , in Star Trek : The Eugenics Wars , Greg Cox refers to the bolognium shielding of Klingon warp nacelles | Bombastium | Disney | Originally appearing in Uncle Scrooge # 17 ( 1957 ) by Carl Barks , Bombastium is stated to be the rarest element in the world . Even though it is very coveted , its usage potential is not entirely known . One characteristic is that it tastes different every time one tries it , and scientists eventually discovered that one atom of bombastium dropped into a barrel of water becomes one barrel of ice cream : a different flavor of ice cream each time . To avoid evaporation , bombastium must be kept frozen . In the story , when this totally new element was discovered Scrooge tries to secure the entire supply - a ball of Bombastium approximately the size of a large turnip . Terrified that his acquisition will melt before he can make a profit , Scrooge drags Donald Duck and his nephews on a voyage to the South Pole to safeguard his investment , but he has not reckoned on the ruthless determination of the Brutopian agents he outbid to achieve it . Bombastium represents a play on words ( bomb and bombastic ) that negotiates Cold War hysteria surrounding the arms race and the threat of Armageddon provoked by the development of the H-bomb . Barks 's tale is also grounded in fears . The substance is later used in the Duck Tales series | Bureaucratium | Scientific in-joke | Similar to Administratium and variation of the joke . In this version of the joke , Bureaucratium is an element which has a negative half-life , becoming more massive and sluggish as time goes by
