  2. Nickel - Wikipedia

    en.wikipedia.org/wiki/Nickel

    As a compound, nickel has a number of niche chemical manufacturing uses, such as a catalyst for hydrogenation, cathodes for rechargeable batteries, pigments and metal surface treatments. [17] Nickel is an essential nutrient for some microorganisms and plants that have enzymes with nickel as an active site .

  3. 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).

  4. 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 ...

  5. Native metal - Wikipedia

    en.wikipedia.org/wiki/Native_metal

    [citation needed] Over geological time scales, very few metals can resist natural weathering processes like oxidation, so mainly the less reactive metals such as gold and platinum are found as native metals. The others usually occur as isolated pockets where a natural chemical process reduces a common compound or ore of the metal, leaving the ...

  6. 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 ...

  7. Nickel double salts - Wikipedia

    en.wikipedia.org/wiki/Nickel_double_salts

    Nickel is one of the metals that can form Tutton's salts. The singly charged ion can be any of the full range of potassium, rubidium, cesium, ammonium (), or thallium. [1] As a mineral the ammonium nickel salt, (NH 4) 2 Ni(SO 4) 2 · 6 H 2 O, can be called nickelboussingaultite. [2]

  8. Properties of nonmetals (and metalloids) by group - Wikipedia

    en.wikipedia.org/wiki/Properties_of_nonmetals...

    Nonmetals show more variability in their properties than do metals. [1] Metalloids are included here since they behave predominately as chemically weak nonmetals.. Physically, they nearly all exist as diatomic or monatomic gases, or polyatomic solids having more substantial (open-packed) forms and relatively small atomic radii, unlike metals, which are nearly all solid and close-packed, and ...

  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.
