  2. File:The Periodic Table of the Elements in Pictures.pdf

    en.wikipedia.org/wiki/File:The_Periodic_Table_of...

    English: This pictorial periodic table is colorful, boring, and packed with information. In addition to the element's name, symbol, and atomic number, each element box has a drawing of one of the element's main human uses or natural occurrences. The table is color-coded to show the chemical groupings.

  3. List of chemical elements - Wikipedia

    en.wikipedia.org/wiki/List_of_chemical_elements

    A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...

    These elements already have images but they are not the highest quality. These elements aren't too rare, so it shouldn't be too hard to find other pictures. Google's probably the best bet here but it may also be worth asking one of Wikipedia's element photographers (a certain person comes to mind) to see if they can get a better photo. Barium ...

  5. List of chemical elements named after places - Wikipedia

    en.wikipedia.org/wiki/List_of_chemical_elements...

    This list of chemical elements named after places includes elements named both directly and indirectly for places. 41 of the 118 chemical elements have names associated with, or specifically named for, places around the world or among astronomical objects.

  6. 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.

  8. Periodic table - Wikipedia

    en.wikipedia.org/wiki/Periodic_table

    Each chemical element has a unique atomic number (Z— for "Zahl", German for "number") representing the number of protons in its nucleus. [4] Each distinct atomic number therefore corresponds to a class of atom: these classes are called the chemical elements. [5] The chemical elements are what the periodic table classifies and organizes.

  9. Chalcogen - Wikipedia

    en.wikipedia.org/wiki/Chalcogen

    The chalcogens (ore forming) (/ ˈ k æ l k ə dʒ ə n z / KAL-kə-jənz) are the chemical elements in group 16 of the periodic table. [1] This group is also known as the oxygen family. Group 16 consists of the elements oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and the radioactive elements polonium (Po) and livermorium (Lv). [2]
