some more ideas
-matter, as there is antimatter
-quarks, what make up protons, neutrons and electrons
-energy, the basis of all elements
-dark matter, an invisible element that has strange properties
Here are some more that could help:
-helium ,drifts upwards
-nitrogen ,stops rusing of iron ,inert gas
-corundum ,almost indestructible ,breaks with exreme pressure
-plastic , just plastic ,formed by oil
-aluminium ,strong,doesnt rust and when mixed with oxygen under high heat and pressure turns into corundum
-juice ,liquidated plant ,heals stickman
-radio waves , type of energy
-neptunium ,in the decay chain of uranium ,radioactive
-calcium ,reacts with water ,gives of some heat ,easily breakable
-francium , extreme explosive reacts with nearly anything i.e. anything not indestructable , short half life
-osmium ,very dense and brittle
-alkali ,neutralises acid ,can dissolve materials
-fluorine ,highly reactive gas
-silver ,shiny, high electrical conductivity and heat conductivity
-tin , low melting point, doesnt rust but attaked by acids and alkalis
thats the most I can think of ,I may think of more
-Helium: Uses?
-Nitrogen: We have GOLD for that.
-Corundum: Alloys.
-Plastic: Seriously? Just, seriously?
-Alumin(i)um: I just don't understand anymore.
-Juice: tpt.el.plnt.grav=1 tpt.el.plnt.diffusion=1
-Radio Waves: Uses? Also, we've already developed radio technology.
-Neptunium: Plutonium. Uranium is inert (except for heating under pressure), and plutonium itself turns to uranium.
-Calcium: This is Powder Toy, not Science Toy.
-Francium: Read Calcium
-Osmium: Read Calcium
-Alkali: Read Calcium
-Fluorine: Read Calcium
-Silver: Tungsten, plus electrical and heat conduction doesn't really matter, as the regular heating is as fast as it goes.
-Tin: Regular metal.
we could have breakable void
