English - English
An extract; a preparation
A one-dimensional value assigned to an object, situation, or state, that can usually be positive or negative
The number of arguments that a verb can have, including the subject of the verb in the counting, ranging from zero (for the likes of "It rains") to three (for the likes of "He gives her a flower")
Alternative spelling of valance
The number of binding sites of a molecule, such as an antibody or antigen
The combining capacity of an atom, radical or functional group determined by the number of electrons that it will lose, gain, or share when it combines with other atoms etc
(Psikoloji, Ruhbilim) The degree of attraction or aversion that an individual feels toward a specific object or event

psychology term.

(chemistry) a property of atoms or radicals; their combining power given in terms of the number of hydrogen atoms (or the equivalent) (biology) a relative capacity to unite or react or interact as with antigens or a biological substrate
A small positive or negative whole number, also called oxidation number, which indicates the net number of electrons gained or lost in the formation of an ion, or the number of electrons the substance can donate or accept in a chemical reaction, and thus the numbers of each kind of ion necessary for a balanced chemical reaction For example, two hydrogen ions (each with a valence of +1) must be present for each ion of oxygen (-2) to form a molecule of water (H2O)
Number of bonds (see bonding) an atom can form. Hydrogen (H) always has valence 1, so other elements' valences equal the number of hydrogen atoms they combine with. Thus, oxygen (O) has valence 2, as in water (H2O); nitrogen (N) has valence 3, as in ammonia (NH3); and chlorine (Cl) has valence 1, as in hydrochloric acid (HCl). The valence depends on the number of unpaired electrons in the outermost (and, in transition elements, the next) shell of the atom's structure. The sharing of the unpaired (valence) electrons in a bond mimics the stable configuration of the noble gases, whose outer shells are full. Elements that can achieve stable configurations by various combinations have more than one valence
The expected value of work outcomes; the extent to which they are attractive or unattractive [5]
{i} chemical parameter related to the external electric charge of an atom or compound which gives an indication of its combining capacity (Chemistry)
The electrons occupying the highest principle energy level in an atom
The combining power of an atom; its capacity to combine with other atoms to form a molecule, expressed in terms of the number of hydrogen atoms or their equivalent with which any atom may combine
 Of a verb definition, an indication of the number of noun operands that the definition can accept: monadic if 1, dyadic if 2, dual-valence if either 1 or 2
The capacity of an atom or group of atoms to combine in specific proportions with other atoms or groups of atoms A valence electron is in the outer or next outer shell of an atom and can participate in forming chemical bonds with other atoms
The chemical conbining capacity of an element or ion
The expected value of work outcomes; the extent to which they are attractive or unattractive
(chemistry) a property of atoms or radicals; their combining power given in terms of the number of hydrogen atoms (or the equivalent)
In °covalent compounds, the valence of an atom is the number of bonds it forms to other atoms
the number of electrons that are used by an atom to form a compound, e g , magnesium generally has two electrons available to be donated and has a valence of 2 Some atoms can have more than one valence, for example iron can have a valence of 2 or 3
with which it will combine, or for which it can be substituted, or with which it can be compared; thus, an atom of hydrogen is a monad, and has a valence of one; the atoms of oxygen, nitrogen, and carbon are respectively dyads, triads, and tetrads, and have a valence respectively of two, three, and four
Also valence band or valence electrons; the electrons in the outermost orbit
The degree of combining power of an atom (or radical) as shown by the number of atoms of hydrogen (or of other monads, as chlorine, sodium, etc
The fringes on a blanket
(biology) a relative capacity to unite or react or interact as with antigens or a biological substrate
The number of arguments that a verb can have (e.g. intransitive verbs only have one, transitive verbs have two, etc)
the relative ability of a biological substance to react or combine; a positive number that characterizes the combining power of an element for other elements, as measured by the number of bonds to other atoms which one atom of the given element forms upon chemical combination – hydrogen is assigned valence 1, and the valence is the number of hydrogen atoms, or their equivalent, with which an atom of the given element combines
Number of excess or deficient electrons an atom or molecule may have in a certain state Indicates the charge of an atom
The number of faces meeting at a vertex
In a graph, the number of (local) ends of segments which meet at a vertex (Another term for the valence of a vertex is its degree )
