From Latin fluor meaning "a flowing", from mineral name fluorspar (calcium fluoride). Fluorspar was used to make iron flowing in smelting. Neon (Ne) 10 νέος (neos) Greek "new" From Greek νέος (neos), meaning "new". Sodium (Na) 11 soda: English From the English "soda", used in names for sodium compounds such as caustic soda, soda ash ...
The most reactive metals, such as sodium, will react with cold water to produce hydrogen and the metal hydroxide: 2 Na (s) + 2 H 2 O (l) →2 NaOH (aq) + H 2 (g) Metals in the middle of the reactivity series, such as iron , will react with acids such as sulfuric acid (but not water at normal temperatures) to give hydrogen and a metal salt ...
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]
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.
Sodium is a chemical element; it has symbol Na (from Neo-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 23 Na. The free metal does not occur in nature and must be prepared from compounds.
Explosive reaction of sodium in water, shattering the glass vessel. The reaction can be extremely violent with alkali metals as the hydrogen gas catches fire. [2] Metals like gold and silver, which are below hydrogen in the reactivity series, do not react with water.

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.
