The Global Liveability rank Ranking is a yearly assessment published by the Economist Intelligence Unit (EIU), ranking 172 global cities (previously 140) for their urban quality of life based on assessments of stability, healthcare, culture and environment, education and infrastructure. Austria's capital, Vienna, was ranked the most liveable ...

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 ...
EIU Global Liveability Index: The most prominent international cost-of-living index is the Economist Intelligence Unit’s annual Global Liveability Index, which wasn’t published in 2020 due to ...
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 ...
In nuclear physics, the island of stability is a predicted set of isotopes of superheavy elements that may have considerably longer half-lives than known isotopes of these elements. It is predicted to appear as an "island" in the chart of nuclides, separated from known stable and long-lived primordial radionuclides.
The livability index represents a wide range of factors for a location, coinciding with the city’s quality of life. For each city a number of factors were sourced including total population ...
e. The dividing line between metals and nonmetals can be found, in varying configurations, on some representations of the periodic table of the elements (see mini-example, right). Elements to the lower left of the line generally display increasing metallic behaviour; elements to the upper right display increasing nonmetallic behaviour.
