Einsteinium is a synthetic chemical element; it has symbol Es and atomic number 99. It was named in honor of Albert Einstein and is a member of the actinide series and is the seventh transuranium element. Einsteinium was discovered as a component of the debris of the first hydrogen bomb explosion in 1952.
The periodic table is a tabular arrangement of the chemical elements, organized by their atomic number, electron configuration, and chemical properties. It is a useful tool for understanding the patterns and trends of the elements and their interactions. Learn more about the history, structure, and significance of the periodic table on Wikipedia.
List of chemical elements. 118 chemical elements have been identified and named officially by IUPAC. 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]
Shinto. The torii gateway to the Itsukushima Shrine in Hiroshima Prefecture, Japan, one of the most famous examples in the country. [ 1] Torii mark the entrance to Shinto shrines and are recognizable symbols of the religion. Shinto ( Japanese: 神道, romanized : Shintō) is a religion originating in Japan.

Chromium is the 21st [38] most abundant element in Earth's crust with an average concentration of 100 ppm. It is also the seventh most abundant element on earth. [39] Chromium compounds are found in the environment from the erosion of chromium-containing rocks, and can be redistributed by volcanic eruptions.
List of elements by stability of isotopes. Isotope half-lives. The darker more stable isotope region departs from the line of protons (Z) = neutrons (N), as the element number Z becomes larger. This is a list of chemical elements by the stability of their isotopes. Of the first 82 elements in the periodic table, 80 have isotopes considered to ...
Shintō Musō-ryū, or Shindō Musō-ryū (神道夢想流) [1] is a traditional ( ko-ryū) school of the Japanese martial art of jōjutsu, the art of handling the Japanese short staff ( jō ). The art was created with the purpose of defeating a swordsman in combat using the jō, with an emphasis on proper distance, timing and concentration.
A chemical element is a chemical substance that cannot be broken down into other substances by chemical reactions. The basic particle that constitutes a chemical element is the atom. Elements are identified by the number of protons in their nucleus, [ 1] known as the element's atomic number. [ 2] For example, oxygen has an atomic number of 8 ...
