The Intensity 7 ( 震度7, Shindo 7) is the maximum intensity in the Japan Meteorological Agency seismic intensity scale, covering earthquakes with an instrumental intensity (計測震度) of 6.5 and up. [ 15] At Intensity 7, it becomes impossible to move at will. [ 13] The intensity was created following the 1948 Fukui earthquake.
Shinzo Abe. a. ^ The Nippon Kaigi is not a political party but a non-government organization and lobbying group. Shinzo Abe ( / ˈʃɪnzoʊ ˈɑːbeɪ / SHIN-zoh AH-bay; Japanese: 安倍 晋三, Hepburn: Abe Shinzō, IPA: [abe ɕindzoː]; 21 September 1954 – 8 July 2022) was a Japanese politician who served as Prime Minister of Japan and ...
This list of countries by life expectancy provides a comprehensive list of countries alongside their respective life expectancy figures. The data is differentiated by sex, presenting life expectancies for males, females, and a combined average. In addition to sovereign nations, the list encompasses several non-sovereign entities and territories.
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]
Livermorium. Livermorium is a synthetic chemical element; it has symbol Lv and atomic number 116. It is an extremely radioactive element that has only been created in a laboratory setting and has not been observed in nature. The element is named after the Lawrence Livermore National Laboratory in the United States, which collaborated with the ...
Chromium is the third hardest element after carbon and boron. Its Mohs hardness is 8.5, which means that it can scratch samples of quartz and topaz , but can be scratched by corundum . Chromium is highly resistant to tarnishing , which makes it useful as a metal that preserves its outermost layer from corroding , unlike other metals such as ...
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 be stable. [1] Overall, there are 251 known stable isotopes in ...
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.
