Webster's 1828 Dictionary

ATOMIC, ATOMICAL

a.Pertaining to atoms; consisting of atoms; extremely minute. The atomical philosophy, said to be broached by Moschus, before the Trojan war, and cultivated by Epicurus, teaches that atoms are endued with gravity and motion, by which all things were formed, without the aid of a supreme intelligent Being.
The atomic theory, in chimistry, or the doctrine of definite proportions, teaches that all chimical combinations take place between the ultimate particles or atoms of bodies, and that these unite either atom with atom, or in proportions expressed by some simple multiple of the number of atoms.

 

Webster's 1913 Dictionary

ATOMIC; ATOMICAL

A *tom "ic, A *tom "ic *al, a. Etym: [Cf. F. atomique. ]

 

1. Of or pertaining to atoms.

 

2. Extremely minute; tiny. 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.

 

ATOMICALLY

ATOMICALLY A *tom "ic *al *ly, adv.

 

Defn: In an atomic manner; in accordance with the atomic philosophy.

 

ATOMICIAN

ATOMICIAN At `o *mi "cian, n.

 

Defn: An atomist. [R.]

 

ATOMICISM

ATOMICISM A *tom "i *cism, n.

 

Defn: Atomism. [Obs. ]

 

ATOMICITY

At `o *mic "i *ty, n. Etym: [Cf. F. atomicité.] (Chem. )

 

Defn: Degree of atomic attraction; equivalence; valence; also (a later use ) the number of atoms in an elementary molecule. See Valence.

atomic

a tom ic |əˈtämik əˈtɑmɪk | ▶adjective of or relating to an atom or atoms: the atomic nucleus. • Chemistry (of a substance ) consisting of uncombined atoms rather than molecules: atomic hydrogen. • of or forming a single irreducible unit or component in a larger system: a society made up of atomic individuals pursuing private interests. • relating to, denoting, or using the energy released in nuclear fission or fusion: the atomic age required a new way of political thinking | atomic weapons. DERIVATIVES a tom i cal ly |-ik (ə )lē |adverb ORIGIN late 17th cent.: from modern Latin atomicus, from atomus ‘indivisible ’ (see atom ).

atomicity

at o mic i ty |ˌatəˈmisitē ætəmˈɪsɪti | ▶noun 1 Chemistry the number of atoms in the molecules of an element. 2 the state or fact of being composed of indivisible units.

 

atomic mass

a tom ic mass |əˈtɑmɪk mæs | ▶noun the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number ) or to the average number allowing for the relative abundances of different isotopes.

 

atomic mass unit

a tom ic mass u nit (abbr.: amu ) ▶noun a unit of mass used to express atomic and molecular weights, equal to one-twelfth of the mass of an atom of carbon-12. It is equal to approximately 1.66 x 10 -27 kg.

 

atomic number

atomic spectrum

a tom ic spec trum |əˈtɑmɪk ˈspɛktrəm | ▶noun the spectrum of frequencies of electromagnetic radiation emitted or absorbed during transitions of electrons between energy levels within an atom. Each element has a characteristic spectrum by which it can be recognized.

 

atomic theory

a tom ic the o ry |əˈtɑmɪk ˈθɪəri | ▶noun the theory that all matter is made up of tiny indivisible particles (atoms ). According to the modern version, the atoms of each element are effectively identical, but differ from those of other elements, and unite to form compounds in fixed proportions. • in any field, a theory that proposes the existence of distinct, separable, independent components: an atomic theory of heredity.

 

atomic volume
