  2. Electronegativity - Wikipedia

    en.wikipedia.org/wiki/Electronegativity

    Electropositivity is a measure of an element's ability to donate electrons, and therefore form positive ions; thus, it is antipode to electronegativity. Mainly, this is an attribute of metals , meaning that, in general, the greater the metallic character of an element the greater the electropositivity.

  3. Bent's rule - Wikipedia

    en.wikipedia.org/wiki/Bent's_rule

    Bent's rule can be extended to rationalize the hybridization of nonbonding orbitals as well. On the one hand, a lone pair (an occupied nonbonding orbital) can be thought of as the limiting case of an electropositive substituent, with electron density completely polarized towards the central atom.

  4. Zinc compounds - Wikipedia

    en.wikipedia.org/wiki/Zinc_compounds

    Zn 2+ is a class A acceptor in the classification of Ahrland, Chatt and Davies, [16] and so forms stronger complexes with the first-row donor atoms oxygen or nitrogen than with second-row sulfur or phosphorus. In terms of HSAB theory Zn 2+ is a hard acid. In aqueous solution an octahedral complex, [Zn(H 2 O) 6] 2+ is the predominant species. [17]

  5. 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.

  6. List of chemical elements - Wikipedia

    en.wikipedia.org/wiki/List_of_chemical_elements

    Like the periodic table, the list below organizes the elements by the number of protons in their atoms; it can also be organized by other properties, such as atomic weight, density, and electronegativity. For more detailed information about the origins of element names, see List of chemical element name etymologies.

  8. Group 12 element - Wikipedia

    en.wikipedia.org/wiki/Group_12_element

    However, beryllium and magnesium are small atoms, unlike the heavier alkaline earth metals and like the group 12 elements (which have a greater nuclear charge but the same number of valence electrons), and the periodic trends down group 2 from beryllium to radium (similar to that of the alkali metals) are not as smooth when going down from ...
