Here, we assessed memory for symbols on the periodic table of elements, which could be presented in symbol format (e.g., H) or word format (e.g., Hydrogen), and compared both to memory for meaningless letters (e

Periodic table - Elements, Properties, Periodicity: The periodicity of properties of the elements is caused by the periodicity in electronic structure. The noble gases are chemically unreactive, or nearly so, because their electronic structures are stabl
Skip to elements sorted by links (more useable to non-graphical browsers and handhelds)Skip to site menu on this page. This periodic table of elements provides comprehensive data on the chemical elements including scores of properties, element names in many languages and most known nuclides (...
Image of an alternative spiral periodic table of the elements Spiral form of the periodic table.Note that the standard form of the periodic table usually has hydrogen (H) located in Group 1, as shown here, despite it being a gas while the other compounds are metals. The reason for this ...
Source:Oxygen-16 is formed primarily in the helium fusion process and neon burning process of massive stars. Oxygen-17 is made during the CNO cycle when hydrogen is burned into helium. Oxygen-18 forms when nitrogen-14 from CNO burning fuses with a helium-4 nucleus. Purified oxygen on Earth...
