I am aware of a few possibilities. Most common, probably, is that something is without a set period so it doesn't transpire transpire or occur or whatever in a specific temporal manner. Another, and probably uncommon, possibility is that something is not of the periodic elements...but such use would probably only occur in very rare instances like perhaps in a science fiction story where the author is explaining that something is of alien origin because it is composed of non-periodic elements.
Reactivity increases the farther down you go in the Periodic Table.

A tsunami could occur at any time, as they are often triggered by something like an earthquake. They are not always down to tidal influences.
About 80% of the first 117 elements occur in the nature in a stable manner.
the Periodic Table is something lame you use to work with science.
"hcn" does not occur in a proper periodic table. "HCN" is the molecular formula for a covalent compound named "hydrogen cyanide".
something that happens repeatedly
Elections in the Bahamas often occur every 4 years.
they occur so often that they kill 400000 people a week
