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. Sodium is the sixth most abundant element in the Earth's crust and exists in numerous minerals such as feldspars, sodalite, and halite (NaCl).
The process has a high energy consumption, for example around 2,500 kWh (9,000 MJ) of electricity per tonne of sodium hydroxide produced. Because the process yields equivalent amounts of chlorine and sodium hydroxide (two moles of sodium hydroxide per mole of chlorine), it is necessary to find a use for these products in the same proportion.
In 2013, compounds of sodium and chloride of different stoichiometries have been discovered; five new compounds were predicted (e.g., Na 3 Cl, Na 2 Cl, Na 3 Cl 2, NaCl 3, and NaCl 7). The existence of some of them has been experimentally confirmed at high pressures and other conditions: cubic and orthorhombic NaCl 3 , two-dimensional metallic ...
Thirty-four teams in NFL history have started a season 9-0. The Chiefs’ plus-58 point differential is the lowest of any of them. Their total margin of victory is barely a quarter of the plus-208 ...
Leonard completed 23 of 32 attempts for 201 yards against the Hoosiers but only 3.8 yards per attempt against Georgia, though he did run for a team-high 80 yards in the 23-10 win. Allar has been ...
