  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. Beryllium - Wikipedia

    en.wikipedia.org/wiki/Beryllium

    Beryllium is used at the Joint European Torus nuclear-fusion research laboratory, and it will be used in the more advanced ITER to condition the components which face the plasma. [113] Beryllium has been proposed as a cladding material for nuclear fuel rods, because of its good combination of mechanical, chemical, and nuclear properties. [18]

  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. Group 2 organometallic chemistry - Wikipedia

    en.wikipedia.org/wiki/Group_2_organometallic...

    Organoberyllium chemistry is limited due to the cost and toxicity of beryllium. Calcium is nontoxic and cheap but organocalcium compounds are difficult to prepare, strontium and barium compounds even more so. One use for these type of compounds is in chemical vapor deposition.

  6. Alkaline earth metal - Wikipedia

    en.wikipedia.org/wiki/Alkaline_earth_metal

    Beryllium occurs in the Earth's crust at a concentration of two to six parts per million (ppm), [56] much of which is in soils, where it has a concentration of six ppm. Beryllium is one of the rarest elements in seawater, even rarer than elements such as scandium, with a concentration of 0.2 parts per trillion.

  7. Electron affinity (data page) - Wikipedia

    en.wikipedia.org/wiki/Electron_affinity_(data_page)

    Electron affinity can be defined in two equivalent ways. First, as the energy that is released by adding an electron to an isolated gaseous atom. The second (reverse) definition is that electron affinity is the energy required to remove an electron from a singly charged gaseous negative ion.

  8. Alkali metal - Wikipedia

    en.wikipedia.org/wiki/Alkali_metal

    Electronegativity is a chemical property that describes the tendency of an atom or a functional group to attract electrons (or electron density) towards itself. [101] If the bond between sodium and chlorine in sodium chloride were covalent , the pair of shared electrons would be attracted to the chlorine because the effective nuclear charge on ...
