Doctrine of definite proportions
(gcide) | Atomic \A*tom"ic\, Atomical \A*tom"ic*al\, a. [Cf. F. atomique.]
1. Of or pertaining to atoms.
[1913 Webster]
2. Extremely minute; tiny.
[1913 Webster]
Atomic bomb, see atom bomb in the vocabulary.
Atomic philosophy, or Doctrine of atoms, a system which,
assuming that atoms are endued with gravity and motion,
accounted thus for the origin and formation of all things.
This philosophy was first broached by Leucippus, was
developed by Democritus, and afterward improved by
Epicurus, and hence is sometimes denominated the Epicurean
philosophy.
Atomic theory, or the Doctrine of definite proportions
(Chem.), teaches that chemical combinations take place
between the supposed ultimate particles or atoms of
bodies, in some simple ratio, as of one to one, two to
three, or some other, always expressible in whole numbers.
Atomic weight (Chem.), the weight of the atom of an element
as compared with the weight of the atom of hydrogen, taken
as a standard.
[1913 Webster] |
Law of definite proportions
(gcide) | Definite \Def"i*nite\, a. [L. definitis, p. p. of definire: cf.
F. d['e]fini. See Define.]
1. Having certain or distinct; determinate in extent or
greatness; limited; fixed; as, definite dimensions; a
definite measure; a definite period or interval.
[1913 Webster]
Elements combine in definite proportions. --Whewell.
[1913 Webster]
2. Having certain limits in signification; determinate;
certain; precise; fixed; exact; clear; as, a definite
word, term, or expression.
[1913 Webster]

class of persons or things; -- also called a definitive.
See Definitive, n. -
Definite inflorescence. (Bot.) See {Determinate
inflorescence}, under Determinate.
Law of definite proportions (Chem.), the essential law of
chemical combination that every definite compound always
contains the same elements in the same proportions by
weight; and, if two or more elements form more than one
compound with each other, the relative proportions of each
are fixed. Compare Law of multiple proportions, under
Multiple.
[1913 Webster] |
law of definite proportions
(wn) | law of definite proportions
n 1: (chemistry) law stating that every pure substance always
contains the same elements combined in the same proportions
by weight [syn: law of constant proportion, {law of
definite proportions}] |
law of equivalent proportions
(wn) | law of equivalent proportions
n 1: (chemistry) law stating that the proportions in which two
elements separately combine with a third element are also
the proportions in which they combine together [syn: {law
of equivalent proportions}, {law of reciprocal
proportions}] |
law of multiple proportions
(wn) | law of multiple proportions
n 1: (chemistry) law stating that when two elements can combine
to form more than one compound the amounts of one of them
that combines with a fixed amount of the other will exhibit
a simple multiple relation [syn: {law of multiple
proportions}, Dalton's law] |
law of reciprocal proportions
(wn) | law of reciprocal proportions
n 1: (chemistry) law stating that the proportions in which two
elements separately combine with a third element are also
the proportions in which they combine together [syn: {law
of equivalent proportions}, {law of reciprocal
proportions}] |
