  2. Reactivity series - Wikipedia

    en.wikipedia.org/wiki/Reactivity_series

    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, such as iron(II) sulfate: Fe (s) + H 2 SO 4 (l) → FeSO 4 (aq) + H 2 (g) There is some ambiguity at the borderlines between the groups.

    This is a list of prices of chemical elements. Listed here are mainly average market prices for bulk trade of commodities. Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison.

  4. Allotropes of arsenic - Wikipedia

    en.wikipedia.org/wiki/Allotropes_of_arsenic

    Reactivity of yellow arsenic with iron complexes featuring bulky cyclopentadienyl moieties, resulting in the formation of butterfly complexes followed sequentially by an As 8 realgar-like central structure linking two iron fragments. [1] [17] The metals of groups 8 and 9 feature the most extensive library of reactivity with yellow arsenic ...

    en.wikipedia.org/wiki/Noble_metal

    "Noble Metals. Gold, Platinum, Silver, and a few rare metals. The members of this class have little or no tendency to unite with oxygen in the free state, and when placed in water at a red heat do not alter its composition. The oxides are readily decomposed by heat in consequence of the feeble affinity between the metal and oxygen." [29]

  7. Periodic table - Wikipedia

    en.wikipedia.org/wiki/Periodic_table

    Periodic table of the chemical elements showing the most or more commonly named sets of elements (in periodic tables), and a traditional dividing line between metals and nonmetals. The f-block actually fits between groups 2 and 3 ; it is usually shown at the foot of the table to save horizontal space.

  9. Water-reactive substances - Wikipedia

    en.wikipedia.org/wiki/Water-reactive_substances

    The alkaline earth metals (Be, Mg, Ca, Sr, Ba, and Ra) are the second most reactive metals in the periodic table, and, like the Group 1 metals, have increasing reactivity with increasing numbers of energy levels. Beryllium (Be) is the only alkaline earth metal that does not react with water or steam, even if the metal is heated red hot. [9]
