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 weights. "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.
Periodic table, Periodic table of the elements (Chem.), A
tabular arrangement of the chemical elements, illustrating
the periodic law, described above.

developed and elaborated by Mendelejeff, whence it is
sometimes called Mendelejeff's law. Important

the hypothetical elements ekaboron, ekaluminium, and

1. In general, a rule of being or of conduct, established by
an authority able to enforce its will; a controlling
regulation; the mode or order according to which an agent
or a power acts.
[1913 Webster]
Note: A law may be universal or particular, written or
unwritten, published or secret. From the nature of the
highest laws a degree of permanency or stability is
always implied; but the power which makes a law, or a
superior power, may annul or change it.

2. In morals: The will of God as the rule for the disposition

3. The Jewish or Mosaic code, and that part of Scripture
where it is written, in distinction from the gospel;

What things soever the law saith, it saith to them
who are under the law . . . But now the
righteousness of God without the law is manifested,

[1913 Webster]
Note: A similar relation had been enunciated in a crude way
by Newlands; but the law in its effective form was
developed and elaborated by Mendelejeff, whence it is
sometimes called Mendelejeff's law. Important
extensions of it were also made by L. Meyer. By this
means Mendelejeff predicted with remarkable accuracy
the hypothetical elements ekaboron, ekaluminium, and
ekasilicon, afterwards discovered and named
respectively scandium, gallium, and germanium.
