Cu with a half-life of 61.83 hours. [24] Seven metastable isomers have been characterized; 68m Cu is the longest-lived with a half-life of 3.8 minutes. Isotopes with a mass number above 64 decay by β −, whereas those with a mass number below 64 decay by β +. 64 Cu, which has a half-life of 12.7 hours, decays both ways. [25] 62 Cu and 64 Cu
Cú Chulainn (/ k uː ˈ k ʌ l ɪ n / koo-KUL-in [1] [2] Irish: [kuːˈxʊlˠɪn̠ʲ] ⓘ), is an Irish warrior hero and demigod in the Ulster Cycle of Irish mythology, as well as in Scottish and Manx folklore. [3]
Copper is a chemical element with the symbol Cu (from Latin: cuprum) and the atomic number of 29. It is easily recognisable, due to its distinct red-orange color.Copper also has a range of different organic and inorganic salts, having varying oxidation states ranging from (0,I) to (III).
The origins of the planetary symbols can be found in the attributes given to classical deities. The Roman planisphere of Bianchini (2nd century, currently in the Louvre, inv. Ma 540) [2] shows the seven planets represented by portraits of the seven corresponding gods, each a bust with a halo and an iconic object or dress, as follows: Mercury has a caduceus and a winged cap; Venus has a ...

41 of the 118 known elements have names associated with, or specifically named for, places around the world or among astronomical objects. 32 of these have names tied to the places on Earth, and the other nine are named after to Solar System objects: helium for the Sun; tellurium for the Earth; selenium for the Moon; mercury (indirectly), uranium, neptunium and plutonium after their respective ...
Both stable isotopes of copper (63 Cu and 65 Cu) have nuclear spin of 3/2−, and thus produce nuclear magnetic resonance spectra, although the spectral lines are broad due to quadrupolar broadening. 63 Cu is the more sensitive nucleus while 65 Cu yields very slightly narrower signals.
Scáthach, illustrated by Beatrice Elvery, from Heroes of the Dawn, 1914 [1]. Scáthach (Irish: [ˈsˠkaːhəx]) or Sgàthach (Scottish Gaelic: Sgàthach an Eilean Sgitheanach) is a figure in the Ulster Cycle of Irish mythology.
