Silver tetrafluoroborate Silver tetrafluoroborate Silver tetrafluoroborate is an inorganic compound with the chemical formula AgBF. It is a white solid that dissolves in polar organic solvents as well as water. In its solid state, the Ag centers are bound to fluoride. Silver tetrafluoroborate is prepared by the reaction between boron trifluoride and silver oxide in the presence of benzene. In the inorganic and organometallic chemistry laboratory, silver tetrafluoroborate, sometimes referred to "silver BF-4", is a useful reagent. In dichloromethane, silver tetrafluoroborate is a moderately strong oxidant. Similar to silver hexafluorophosphate, it is commonly used to replace halide anions or ligands with the
Term symbol database, neutral atoms are identified as I, singly ionized atoms as II, etc. Neutral atoms of the chemical elements have the same term symbol "for each column" in the s-block and p-block elements, but may differ in d-block and f-block elements, if the ground state electron configuration changes within a column. Ground state term symbols for chemical elements are given below. For light atoms, the spin-orbit interaction (or coupling) is small so that the total orbital angular momentum "L" and total spin "S" are good quantum numbers. The interaction between "L" and "S" is known as "LS coupling," "Russell-Saunders" "coupling"
