  2. Electronegativities of the elements (data page) - Wikipedia

    en.wikipedia.org/wiki/Electronegativities_of_the...

    Electronegativity is not a uniquely defined property and may depend on the definition. The suggested values are all taken from WebElements as a consistent set. Many of the highly radioactive elements have values that must be predictions or extrapolations, but are unfortunately not marked as such.

  3. Electronegativity - Wikipedia

    en.wikipedia.org/wiki/Electronegativity

    In inorganic chemistry, it is common to consider a single value of electronegativity to be valid for most "normal" situations. While this approach has the advantage of simplicity, it is clear that the electronegativity of an element is not an invariable atomic property and, in particular, increases with the oxidation state of the element. [30]

  4. List of elements by atomic properties - Wikipedia

    en.wikipedia.org/wiki/List_of_elements_by_atomic...

    This is a list of chemical elements and their atomic properties, ordered by atomic number (Z).. Since valence electrons are not clearly defined for the d-block and f-block elements, there not being a clear point at which further ionisation becomes unprofitable, a purely formal definition as number of electrons in the outermost shell has been used.

  5. Reactivity series - Wikipedia

    en.wikipedia.org/wiki/Reactivity_series

    The image shows a periodic table extract with the electronegativity values of metals. [12] Wulfsberg [13] distinguishes: very electropositive metals with electronegativity values below 1.4 electropositive metals with values between 1.4 and 1.9; and electronegative metals with values between 1.9 and 2.54.

    See also: Electronegativities of the elements (data page) There are no reliable sources for Pm, Eu and Yb other than the range of 1.1–1.2; see Pauling, Linus (1960).

  7. Aluminium - Wikipedia

    en.wikipedia.org/wiki/Aluminium

    Aluminium (or aluminum in North American English) is a chemical element; it has symbol Al and atomic number 13. Aluminium has a density lower than that of other common metals , about one-third that of steel .

  8. Post-transition metal - Wikipedia

    en.wikipedia.org/wiki/Post-transition_metal

    Scatter plot of electronegativity values and melting points for metals (up to fermium, element 100) and some borderline elements (Ge, As, Se, Sb, Te, At). Elements categorised by some authors as post-transition metals are distinguished by their relatively high electronegativity values, and relatively low melting points (Pt is anomalous in this ...

  9. Aluminium compounds - Wikipedia

    en.wikipedia.org/wiki/Aluminium_compounds

    Aluminium (British and IUPAC spellings) or aluminum (North American spelling) combines characteristics of pre- and post-transition metals. Since it has few available electrons for metallic bonding, like its heavier group 13 congeners, it has the characteristic physical properties of a post-transition metal, with longer-than-expected interatomic ...
