  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. 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 ...

  6. Heavy metal element - Wikipedia

    en.wikipedia.org/wiki/Heavy_metal_(elements)

    Lithophile heavy metals are mainly f-block elements and the more reactive of the d-block elements. They have a strong affinity for oxygen and mostly exist as relatively low density silicate minerals. [121] Chalcophile heavy metals are mainly the less reactive d-block elements, and period 4–6 p-block metals and metalloids.

  7. Metal - Wikipedia

    en.wikipedia.org/wiki/Metal

    A metal may be a chemical element such as iron; an alloy such as stainless steel; or a molecular compound such as polymeric sulfur nitride. [4] The general science of metals is called metallurgy , a subtopic of materials science ; aspects of the electronic and thermal properties are also within the scope of condensed matter physics and solid ...

  8. 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.

  9. List of chemical elements - Wikipedia

    en.wikipedia.org/wiki/List_of_chemical_elements

    A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
