Most frequently, covalent bonds involving fluorine atoms are single bonds, although at least two examples of a higher order bond exist.Fluoride may act as a bridging ligand between two metals in some complex molecules.ith other atoms, fluorine forms either polar covalent bonds or ionic bonds.

There are three sequences stacked in official sport stacking events, that are defined by the rule book handed out by the WSSA: 1  3-3-3: Uses nine cups. This sequence consists of three sets of three cups each. 2  3-6-3: Uses 12 cups. This sequence is similar to the 3-3-3, except a six stack replaces the three stack in the middle. 3  Cycle: Uses 12 cups.
