So I was curious about what the chemical structure of Redstone looks like, and Minecraft Education Edition, albeit unintentionally, gives us a canon look into what Redstone is made of:




In Minecraft Education Edition, putting a Redstone Block into a Material Reducer shows that it's composed of 31 Carbon, 31 Uranium, and 38 Unobtanium, which we can assume to be measured in grams



Dividing the Redstone Block into Redstone Dust, each Redstone Dust is then composed of approximately 3.4 Carbon, 3.4 Uranium, and 4.2 Unobtanium



Again assuming that's measured in grams, that's 0.17 cm³ of Uranium, 1.496 cm³ of Carbon, and ???³ of Unobtanium per Redstone Dust



So what does this tell us about the chemical structure of Redstone? Basing this on Redstone Dust's composition, we can estimate that each Redstone molecule is composed of 3 Carbon atoms, 3 Uranium atoms, 4 Unobtanium atoms, a little under half of the time it binds to an extra Uranium and/or Carbon, and 20% of the time it binds to an extra Unobtanium



This also has some horrifying implications for how Redstone works:



Redstone would be extremely volatile as the radioactive decay from Unobtanium and Uranium would occasionally release Helium ions through alpha radiation, sometimes breaking apart Carbon into two Beryllium atoms (as it absorbs the extra proton and neutron from the Uranium) or merging into Oxygen



So Redstone should, in theory, be extremely flammable and potentially explosive, which implies that cave static, or the player mining Redstone with an Iron Pickaxe, could lead to a spark that causes an explosive cave-in



As Unobtanium is just a placeholder for unobtainable elements (hence the name), I'm going to estimate Unobtanium in this case as Unbinilium, the placeholder name for element 120



Why?




I'm estimating the Unobtanium as Redstone as being larger than the largest man-made element, Oganesson, which holds an impressive 118 protons



Each valence electron shell, from innermost to outermost, can bind with 2, 8, 18, 32, 32, 18, and 8 shells respectively, so I'd like Unobtanium to be an element we haven't discovered yet, and consequently I'd like to jump up to the next shell



While I could estimate with element 119's placeholder, Ununennium, it would have one electron in the next shell, so Unbinilium allows for easier chemical binding



So what does this molecule look like then? Well, horrifyingly...




It looks like this. As Redstone forms in crystal lattices, and only two Carbon atoms are free to bind, I can absolutely see why it's so brittle that it breaks into powder.



This makes the structure of Redstone:



C3U3Uno4 (55% of molecules)
C4U3Uno4 (13% of molecules)
C3U4Uno4 (13% of molecules)
C4U4Uno4 (7% of molecules)
C3U3Uno5 (5% of molecules)
C4U3Uno5 (3% of molecules)
C3U4Uno5 (3% of molecules)
C4U4Uno5 (1% of molecules)



An extremely radioactive, flammable, and explosive compound.
