Sculpture at NordArt. NordArt is an international contemporary art exhibition and a non-profit cultural initiative of the ACO Group and the cities of Büdelsdorf and Rendsburg. It has taken place annually in the summer since 1999 at Carlshütte, a former iron foundry. The site features 22,000 m² of interior space and 60,000 m² for outdoor ...
The periodic table, also known as the periodic table of the elements, is an ordered arrangement of the chemical elements into rows (" periods ") and columns (" groups "). It is an icon of chemistry and is widely used in physics and other sciences. It is a depiction of the periodic law, which states that when the elements are arranged in order ...
Art Fund sponsors the Museum of the Year award (known as the Gulbenkian Prize from 2003 to 2007 and the Art Fund Prize from 2008 to 2012). This is a £100,000 prize awarded annually to the museum or gallery that had the most imaginative, innovative or popular project during the previous year. [ 11 ]
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 ...
Thus element 164 with 7d 10 9s 0 is noted by Fricke et al. to be analogous to palladium with 4d 10 5s 0, and they consider elements 157–172 to have chemical analogies to groups 3–18 (though they are ambivalent on whether elements 165 and 166 are more like group 1 and 2 elements or more like group 11 and 12 elements, respectively). Thus ...
The data below tabulates standard electrode potentials (E °), in volts relative to the standard hydrogen electrode (SHE), at: Absolute partial pressure 101.325 kPa (1.00000 atm; 1.01325 bar) for each gaseous reagent — the convention in most literature data but not the current standard state (100 kPa). Variations from these ideal conditions ...
