SB Nation (an abbreviation for their full name SportsBlogs Nation) is a sports blogging network owned by Vox Media. It was co-founded by Tyler Blezinski, Markos Moulitsas , and Jerome Armstrong in 2003.
Antimony is a chemical element; it has symbol Sb (from Latin stibium) and atomic number 51. A lustrous grey metal or metalloid , it is found in nature mainly as the sulfide mineral stibnite (Sb 2 S 3 ).
"Spiritual but not religious" (SBNR), also known as "spiritual but not affiliated" (SBNA), or less commonly "more spiritual than religious" is a popular phrase and initialism used to self-identify a life stance of spirituality that does not regard organized religion as the sole or most valuable means of furthering spiritual growth.
Some examples of antimonates and their structures are shown below: Li 3 SbO 4 has a NaCl superstructure with isolated Sb 4 O 12− 16 units. [3]Sodium antimonate, NaSbO 3, has the ilmenite structure, with hexagonal close packed oxide ions with each ion, Na + and Sb 5+ occupying a third of the octahedral sites.
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
There are also many isomers, the longest-lived of which is 120m1 Sb with half-life 5.76 days. Except for beryllium , antimony is the lightest element observed to have isotopes capable of alpha decay ; 104 Sb is seen to undergo this mode of decay.
The antimonide ion is Sb 3− but the term refers also to any anionic derivative of antimony. [1] Antimonides are often prepared by heating the elements. [2] The reduction of antimony by alkali metals or by other methods leads to alkali metal antimonides of various types. [3] Known antimonides include isolated Sb 3− ions (in Li 3 Sb and Na 3 Sb).
The Na 2 S can be generated in situ by the reaction of sodium hydroxide and S (co-generating sodium sulfate): Sb 2 S 3 + 8 NaOH + 6 S → 2 Na 3 SbS 4 + Na 2 SO 4 + 4 H 2 O. Charcoal can also be used to reduce the sulfur. The required antimony trisulfide is prepared by treatment of Sb(III) compounds with sulfide sources: 2 SbCl 3 + 3 H 2 S → ...
