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 ...
The positive ion retains its element name whereas for a single non-metal anion the ending is changed to -ide. Example: sodium chloride, potassium oxide, or calcium carbonate. When the metal has more than one possible ionic charge or oxidation number the name becomes ambiguous. In these cases the oxidation number (the same as the charge) of the ...
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.
chain reaction charge number A quantized value of electric charge calculated as the electric charge in coulombs divided by the elementary-charge constant, or z = q/e. Charge numbers for ions are denoted in superscript (e.g. Na + indicates a sodium ion with a charge number of positive one). Atomic numbers are charge numbers of atomic nuclei ...
The formation of an alkali metal nitride would consume the ionisation energy of the alkali metal (forming M + ions), the energy required to break the triple bond in N 2 and the formation of N 3− ions, and all the energy released from the formation of an alkali metal nitride is from the lattice energy of the alkali metal nitride.
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]

Sodium metal is highly reducing, with the standard reduction potential for the Na + /Na couple being −2.71 volts, [3] though potassium and lithium have even more negative potentials. [4] The thermal, fluidic, chemical, and nuclear properties of molten sodium metal have caused it to be one of the main coolants of choice for the fast breeder ...
