Ar U SErIOUS? - Random Trivia Answers

• A1) Neon (NeON). The only element that can be spelled using only symbols on the same row on the periodic table (and very close to each other at atomic numbers 7, 8, and 10).
• A2) Tin (TiN). The only element whose name can be spelled using only two symbols, and not coincidentally the shortest name.
• A3) Phosphorus (PHOsPHoRuS, PHoSPHoRuS, PHOSPHoRus, PHOsPHORuS, PHoSPHORuS, or PHOSPHORuS). The element whose name can be spelled the most ways and using the most symbols, and not coincidentally the longest name.
• A4) Carbon (CaRbON or CArBON). The element of the twelve whose symbol appears in the most answers, four. Nitrogen (N) appears in nine of the twelve answers.
• A5) Arsenic (ArSeNiC or ArSeNIC). One of the four elements, along with carbon, neon, and phosphorus, whose symbol can be used to spell one of the other answers.
• A6) Copper (CoPPEr or COPPEr). One of the two elements, along with phosphorus, that requires a repeated symbol.
• A7) Iron (IrON). One of the three elements, along with copper and tin, that cannot use its own symbol in its spelling.
• A8) Bismuth (BiSmUTh or BISmUTh). The element that uses the highest numbered element, uranium (92), as well as the second highest, thorium (90). [Yes, that's what the "Bism-" in "Pepto-Bismol" stands for.]
• A9) Silicon (SiLiCoN, SILiCoN, SiLiCON, or SILiCON). One of the four elements, along with arsenic, bismuth, and carbon, that can be spelled either with or without its own symbol.
• A10) Astatine (AsTaTiNe). The only element whose name can be spelled using only two-letter symbols (but doesn't use its own symbol even though it's a substring).
• A11) Xenon (XeNoN or XeNON). The only element whose name can be spelled either with or without a repeated symbol.
• A12) Krypton (KrYPtON). One of the five elements, along with astatine, neon, phosphorus, and xenon that can't be spelled without using its own symbol.
