Sodium
Sodium is a chemical element with the symbol Na (from Latin ''natrium'') and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table. Its only stable isotope is 23Na. The free metal does not occur in nature, and must be prepared from compounds. Sodium is the sixth most abundant element in the Earth's crust and exists in numerous minerals such as feldspars, sodalite, and halite (NaCl). Many salts of sodium are highly water-soluble: sodium ions have been leached by the action of water from the Earth's minerals over eons, and thus sodium and chlorine are the most common dissolved elements by weight in the oceans. Sodium was first isolated by Humphry Davy in 1807 by the electrolysis of sodium hydroxide. Among many other useful sodium compounds, sodium hydroxide (lye) is used in soap manufacture, and sodium chloride (edible salt) is a de-icing agent and a nutrient for animals including h ...

Nakoku
was a stateIn Japanese, the character 国/國, read as ''koku'' (in on'yomi) or ''kuni'' (in kun'yomi), can be translated as "country" or "province" which was located in and around modern-day Fukuoka City, on the Japanese island of Kyūshū, from the 1st to early 3rd centuries. Much of what is known about it comes from ancient records of both China and Japan. According to the ''Book of the Later Han'', in 57 CE, Emperor Guangwu of Han granted Nakoku an imperial seal, patterned after the Chinese jade seals, but made of gold: the king of Na gold seal. In return, that same year, Na sent envoys to the Chinese capital, offering tribute and formal New Year's greetings. This seal was discovered over 1500 years later, by an Edo period farmer on Shikanoshima Island, thus helping to verify the existence of Nakoku, which was otherwise known only from the ancient chronicles. Engraved upon it are the Chinese characters (''Kan no Wa no Na-no-Koku-ō'', "King of the Na state of the Wa (vass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Na (cuneiform)
The cuneiform na sign is a common, multi-use sign, a syllabic for ''na'', and an alphabetic sign used for ''n'', or ''a''; it is common in both the ''Epic of Gilgamesh'' over hundreds of years, and the 1350 BC Amarna letters. In the ''Epic of Gilgamesh'' it also has sumerogramic (capital letter (majuscule)) usage for NA. An example usage for ''NA'' in the Epic is for the spelling of ''NA.GAD'', (also '' LÚ.NA.GAD'', and the plural '' LÚ.NA.GAD. MEŠ''), for Akkadian language "nāqidu", ''"herdsman"''. The usage for ''NA'' in herdsman is only for 3 spellings. The commonness of cuneiform ''na'', in the top 25 used signs by Buccellati (Buccellati 1979), (2nd highest usage, exceeded by a: ''a (cuneiform)'') is because of usage for the spelling of ''a-na'' (Akkadian language "ana") -, the common preposition spelling for English language: ''to, for, by, of, at, etc.''. It is also a component for the Akkadian language preposition: ''i-na'' (''ina''), meaning: ''in, into, by, etc.''. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
