Defn: Of or pertaining to a period; constituting a complete sentence. Periodic comet (Astron.), a comet that moves about the sun in an elliptic orbit; a comet that has been seen at two of its approaches to the sun. -- Periodic function (Math. ), a function whose values recur at fixed intervals as the variable uniformly increases. The trigonomertic functions, as sin x, tan x, etc. , are periodic functions. Exponential functions are also periodic, having an imaginary period, and the elliptic functions have not only a real but an imaginary period, and are hence called doubly periodic. -- Periodic law (Chem. ), the generalization that the properties of the chemical elements are periodic functions of their atomic wieghts."In other words, if the elements are grouped in the order of their atomic weights, it will be found that nearly the same properties recur periodically throughout the entire series. " The following tabular arrangement of the atomic weights shows the regular recurrence of groups (under I., II., III., IV. , etc. ), each consisting of members of the same natural family. The gaps in the table indicate the probable existence of unknown elements.
