  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.

  3. Galvanic series - Wikipedia

    en.wikipedia.org/wiki/Galvanic_series

    The galvanic series (or electropotential series) determines the nobility of metals and semi-metals. When two metals are submerged in an electrolyte, while also electrically connected by some external conductor, the less noble (base) will experience galvanic corrosion. The rate of corrosion is determined by the electrolyte, the difference in ...

  4. Periodic table - Wikipedia

    en.wikipedia.org/wiki/Periodic_table

    [39] [58] This creates an analogous series in which the outer shell structures of sodium through argon are analogous to those of lithium through neon, and is the basis for the periodicity of chemical properties that the periodic table illustrates: [39] at regular but changing intervals of atomic numbers, the properties of the chemical elements ...

  5. Extended periodic table - Wikipedia

    en.wikipedia.org/wiki/Extended_periodic_table

    The next two elements, elements 119 and 120, should form an 8s series and be an alkali and alkaline earth metal, respectively. Beyond element 120, the superactinide series is expected to begin, when the 8s electrons and the filling of the 8p 1/2 , 7d 3/2 , 6f, and 5g subshells determine the chemistry of these elements.

  6. 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]

  7. Group (periodic table) - Wikipedia

    en.wikipedia.org/wiki/Group_(periodic_table)

    The numbers indicate approximately the highest oxidation number of the elements in that group, and so indicate similar chemistry with other elements with the same numeral. The number proceeds in a linearly increasing fashion for the most part, once on the left of the table, and once on the right (see List of oxidation states of the elements ...

  8. Talk:Reactivity series - Wikipedia

    en.wikipedia.org/wiki/Talk:Reactivity_series

    There should be a reactivity number. The reactivity number range from 0-5 or 0-10. Cosmium 23:55, 29 January 2007 (UTC) The Pauling scale rates elements according to electronegativity, while the standard electrode potential chart rates elements according to the force that they give away or accept electrons.

  9. Periodic trends - Wikipedia

    en.wikipedia.org/wiki/Periodic_trends

    However, as we move down in a group, the number of valence electrons generally does not change. Hence, in many cases the elements of a particular group have the same valency. However, this periodic trend is not always followed for heavier elements, especially for the f-block and the transition metals. These elements show variable valency as ...
