  3. Reactivity series - Wikipedia

    en.wikipedia.org/wiki/Reactivity_series

    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 ...

  4. Nickel compounds - Wikipedia

    en.wikipedia.org/wiki/Nickel_compounds

    Nickel compounds are chemical compounds containing the element nickel which is a member of the group 10 of the periodic table. Most compounds in the group have an oxidation state of +2. Nickel is classified as a transition metal with nickel(II) having much chemical behaviour in common with iron(II) and cobalt(II).

  5. Reactivity (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Reactivity_(chemistry)

    In chemistry, reactivity is the impulse for which a chemical substance undergoes a chemical reaction, either by itself or with other materials, with an overall release of energy. Reactivity refers to: the chemical reactions of a single substance, the chemical reactions of two or more substances that interact with each other,

  7. Rieke metal - Wikipedia

    en.wikipedia.org/wiki/Rieke_metal

    The use of highly reactive metals in chemical synthesis was popularized in the 1960s. One development in this theme is the use of metal vapor synthesis, as described by Skell, [citation needed] Timms, [11] Ozin, [citation needed] and others. All of these methods relied on elaborate instrumentation to vaporize the metals, releasing an atomic ...

  8. Nickel(II) fluoride - Wikipedia

    en.wikipedia.org/wiki/Nickel(II)_fluoride

    Nickel(II) fluoride is the chemical compound with the formula NiF 2. It is an ionic compound of nickel and fluorine and forms yellowish to green tetragonal crystals. Unlike many fluorides, NiF 2 is stable in air.

  9. Iron–nickel alloy - Wikipedia

    en.wikipedia.org/wiki/Iron–nickel_alloy

    The surfaces of these metallic compounds provide a complex electron environment for catalyzing chemical reactions. [4] In steel metallurgy, nickel is alloyed with iron since 1888 (date of Schneider et Cie's patent [5] on nickel steel based on Jean Werth's research [6]) to produce maraging steel and some low-alloy steels.
