  2. Tin - Wikipedia

    en.wikipedia.org/wiki/Tin

    Tin can form many oxides, sulfides, and other chalcogenide derivatives. The dioxide SnO 2 (cassiterite) forms when tin is heated in the presence of air. [43] SnO 2 is amphoteric, which means that it dissolves in both acidic and basic solutions. [45] Stannates with the structure [Sn(OH) 6] 2−, like K 2 [Sn(OH) 6], are also known, though the ...

  3. Isotopes of tin - Wikipedia

    en.wikipedia.org/wiki/Isotopes_of_tin

    Tin-121m (121m Sn) is a radioisotope and nuclear isomer of tin with a half-life of 43.9 years. In a normal thermal reactor, it has a very low fission product yield; thus, this isotope is not a significant contributor to nuclear waste. Fast fission or fission of some heavier actinides will produce tin-121 at higher yields. For example, its yield ...

  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. Table of nuclides - Wikipedia

    en.wikipedia.org/wiki/Table_of_nuclides

    A table or chart of nuclides is a two-dimensional graph of isotopes of the elements, in which one axis represents the number of neutrons (symbol N) and the other represents the number of protons (atomic number, symbol Z) in the atomic nucleus. Each point plotted on the graph thus represents a nuclide of a known or hypothetical chemical element.

  6. Chemical symbol - Wikipedia

    en.wikipedia.org/wiki/Chemical_symbol

    Chemical symbols are the abbreviations used in chemistry, mainly for chemical elements; but also for functional groups, chemical compounds, and other entities. Element symbols for chemical elements, also known as atomic symbols, normally consist of one or two letters from the Latin alphabet and are written with the first letter capitalised.

  9. Tin(IV) oxide - Wikipedia

    en.wikipedia.org/wiki/Tin(IV)_oxide

    Tin(IV) oxide, also known as stannic oxide, is the inorganic compound with the formula SnO 2. The mineral form of SnO 2 is called cassiterite , and this is the main ore of tin . [ 9 ] With many other names, this oxide of tin is an important material in tin chemistry.
