Potassium Tantal Fluoride, an intermediary product in refining Tantalum. It is obtained from Coltan (aka Tantalita). Tantalum is the high-value component.
O.S of K = +1 O.S. of Ta = +5 O.S. of F = -1
In K2TaF7, the oxidation number of K is +1, Ta is +5, and F is -1. This is determined by assigning known oxidation numbers to the compounds (K is typically +1 and F is -1) and solving for the unknown ones (Ta).
