  2. Organogermanium chemistry - Wikipedia

    en.wikipedia.org/wiki/Organogermanium_chemistry

    Organogermanium chemistry is the science of chemical species containing one or more C–Ge bonds. Germanium shares group 14 in the periodic table with carbon, silicon, tin and lead.

  3. 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.

  4. Main group organometallic chemistry - Wikipedia

    en.wikipedia.org/wiki/Main_group_organometallic...

    Main group organometallic chemistry are typically categorized according to their position in the periodic table. Another possible classification scheme organizes these compounds according to the nature of the organic substituent: alkyls , aryls , vinyls, etc.

  5. 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.

  6. Period 6 element - Wikipedia

    en.wikipedia.org/wiki/Period_6_element

    A period 6 element is one of the chemical elements in the sixth row (or period) of the periodic table of the chemical elements, including the lanthanides.The periodic table is laid out in rows to illustrate recurring (periodic) trends in the chemical behaviour of the elements as their atomic number increases: a new row is begun when chemical behaviour begins to repeat, meaning that elements ...

  7. Dividing line between metals and nonmetals - Wikipedia

    en.wikipedia.org/wiki/Dividing_line_between...

    In 1891, Walker published a periodic "tabulation" with a diagonal straight line drawn between the metals and the nonmetals. [14] In 1906, Alexander Smith published a periodic table with a zigzag line separating the nonmetals from the rest of elements, in his highly influential [15] textbook Introduction to General Inorganic Chemistry. [16]

  8. Organolanthanide chemistry - Wikipedia

    en.wikipedia.org/wiki/Organolanthanide_chemistry

    Organolanthanide chemistry is the field of chemistry that studies organolanthanides, compounds with a lanthanide-carbon bond. Organolanthanide compounds are different from their organotransition metal analogues in the following ways:

  9. Organomagnesium chemistry - Wikipedia

    en.wikipedia.org/wiki/Organomagnesium_chemistry

    Organomagnesium chemistry, a subfield of organometallic compounds, refers to the study of magnesium compounds that contains Mg-C bonds. Magnesium is the second element in group 2 (alkaline earth metals), and the ionic radius of Mg 2+ is 86 pm, which is larger than Be 2+ (59 pm) and smaller than the heavier alkaline earth metal dications (Ca 2+ 114 pm, Sr 2+ 132 pm, Ba 2+ 149 pm), [1] in ...
