    en.wikipedia.org/wiki/File:Periodic_table_large.svg

    English: An SVG periodic table of the elements, which includes name, atomic mass, electron configuration, first ionization energy, and electronegativity. Esperanto: Perioda tabelo de la elementoj, en SVG, kiu enhavas nomon, atomomason, elektronan konfiguradon, unuan jonigan energion kaj elektronegativecon.

  3. 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.

  4. Crystallographic image processing - Wikipedia

    en.wikipedia.org/wiki/Crystallographic_image...

    All 3D space groups and their subperiodic 2D periodic layer groups (including the above-mentioned 46 two-sided groups) project to just 17 plane space group types, which are genuinely 2D periodic and are sometimes referred to as the wallpaper groups. (Although quite popular, this is a misnomer because wallpapers are not restricted to possess ...

  5. 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.

  6. Oxygen - Wikipedia

    en.wikipedia.org/wiki/Oxygen

    It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and a potent oxidizing agent that readily forms oxides with most elements as well as with other compounds. Oxygen is the most abundant element in Earth's crust, and the third-most abundant element in the universe after hydrogen and helium.

  7. Island of stability - Wikipedia

    en.wikipedia.org/wiki/Island_of_stability

    Proton number Z, also named the atomic number, determines the position of an element in the periodic table. The approximately 3300 known nuclides [7] are commonly represented in a chart with Z and N for its axes and the half-life for radioactive decay indicated for each unstable nuclide (see figure). [8]

  9. Livermorium - Wikipedia

    en.wikipedia.org/wiki/Livermorium

    Livermorium is projected to be the fourth member of the 7p series of chemical elements and the heaviest member of group 16 in the periodic table, below polonium. While it is the least theoretically studied of the 7p elements, its chemistry is expected to be quite similar to that of polonium. [ 4 ]
