Air balloon submerged in liquid nitrogen. Liquid nitrogen is a cryogenic liquid which looks like water. When insulated in proper containers such as dewar flasks, it can be transported and stored with a low rate of evaporative loss. [99] A container vehicle carrying liquid nitrogen. Like dry ice, the main use of liquid nitrogen is
The Latin term, during the Roman Empire, was aes cyprium; aes was the generic term for copper alloys such as bronze. Cyprium means "Cyprus" or "which is from Cyprus", where so much of it was mined; it was simplified to cuprum and then eventually Anglicized as "copper" (Old English coper/copor). · Symbol Cu is from the Latin name cuprum ("copper").
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).
Ruthenium is from the Latin name for the region including Belarus, Ukraine, and Russia. [29] Lutetium is named after Lutetia, the Latin name for Paris. Copper's name comes from an Old English word derived from the Latin name for the island of Cyprus. [30] The names of both magnesium and manganese derive from the Greek region of Magnesia. [31]
Only four radicals are used for elements: 釒 / 钅 (jīn "gold; metal") for solid metals, 石 (shí "stone, rock") for solid non-metals, 水 / 氵 (shuǐ "water") for liquids, and 气 (qì "air, steam") for gases. The phonetic (sound) part represents the character's pronunciation and is a partial transliteration of the element's name.
Planetary names and symbols for the metals – the seven planets and seven metals known since Classical times in Europe and the Mideast – was ubiquitous in alchemy. The association of what are anachronistically known as planetary metals started breaking down with the discovery of antimony, bismuth and zinc in the 16th century.
Solid nitrogen is slightly soluble in liquid hydrogen. Based on solubility in 60–75 K gaseous hydrogen, [13] Seidal et al. estimated that liquid hydrogen at 15 K can dissolve (1–10) × 10 10 (molecule N 2)/cm 3. [14] At the boiling point of hydrogen with excess solid nitrogen, the dissolved molar fraction is 10 −8.
In most cases, Latin names of elements as used by Berzelius have the same roots as the modern English name. For example, hydrogen has the symbol "H" from Neo-Latin hydrogenium, which has the same Greek roots as English hydrogen. However, in eleven cases Latin (as used by Berzelius) and English names of elements have different roots.
