The most reactive metals, such as sodium, will react with cold water to produce hydrogen and the metal hydroxide: 2 Na (s) + 2 H 2 O (l) →2 NaOH (aq) + H 2 (g) Metals in the middle of the reactivity series, such as iron , will react with acids such as sulfuric acid (but not water at normal temperatures) to give hydrogen and a metal salt ...
Cubic boron nitride is insoluble in iron, nickel, and related alloys at high temperatures, but it binds well with metals due to formation of interlayers of metal borides and nitrides. It is also insoluble in most acids, but is soluble in alkaline molten salts and nitrides, such as LiOH, KOH, NaOH/Na 2 CO 3, NaNO 3 which are used to etch c-BN. [32]
Blueish metal, named after the game it features in; also commonly called 'rune'. In earlier versions of the game and the Old School game, it is the toughest workable metal, [73] and in the main game it is both the strongest workable metal in the free-to-play version, as well as being the main ingredient in the Elder Rune metal.

LC200N [58] (aka Z-FiNit, Cronidur30, N360) produced by Zapp Precision Metals, is a high nitrogen alloyed tool steel which exhibits superior corrosion resistance combined with high toughness even at hardness up to 60 HRc. Spyderco uses this steel in several of their knives.
When an alkali metal is dropped into water, it produces an explosion, of which there are two separate stages. The metal reacts with the water first, breaking the hydrogen bonds in the water and producing hydrogen gas; this takes place faster for the more reactive heavier alkali metals. Second, the heat generated by the first part of the ...
The following table provides the reduction potentials of the indicated reducing agent at 25 °C. For example, among sodium (Na), chromium (Cr), cuprous (Cu +) and chloride (Cl −), it is Na that is the strongest reducing agent while Cl − is the weakest; said differently, Na + is the weakest oxidizing agent in this list while Cl is the strongest.
Another metalloid, antimony, features in the strongest known acid, a mixture 10 billion times stronger than carborane acid. This is fluoroantimonic acid H 2 F[SbF 6], a mixture of antimony pentafluoride SbF 5 and hydrofluoric acid HF. [citation needed] Silicon. The thermal conductivity of silicon is better than that of most metals. [citation ...
