Question

What is the defination for valency?

Answer 1

If you mean the chemisty term like I think you so as in valence electrons, its the elcetrons on the outer most part of the atom which does all the bonding and reacting.

Answer 2

va·lence playAudio (vlns) KEY also va·len·cy (-ln-s) KEY



NOUN:

pl. val·lenc·es , also val·len·cies



1. Chemistry

1. The combining capacity of an atom or radical determined by the number of electrons that it will lose, add, or share when it reacts with other atoms.

2. A positive or negative integer used to represent this capacity: The valences of copper are 1 and 2.

2. The number of binding sites of a molecule, such as an antibody or antigen.

3. The ability of a substance to interact with another or to produce an effect.

4. Psychology The degree of attraction or aversion that an individual feels toward a specific object or event.

5. Linguistics The number of arguments that a lexical item, especially a verb, can combine with to make a syntactically well-formed sentence, often along with a description of the categories of those constituents. Intransitive verbs (appear, arrive) have a valence of onethe subject; some transitive verbs (paint, touch), twothe subject and direct object; other transitive verbs (ask, give), threethe subject, direct object, and indirect object.

6. The capacity of something to unite, react, or interact with something else: "I do not claim to know much more about novels than the writing of them, but I cannot imagine one set in the breathing world which lacks any moral valence" (Robert Stone).

Answer 3

Valency refers to the capacity of a verb to take a specific number and type of arguments (noun phrase positions).



The terminology comes from chemistry, in which the valency of a chemical element is its capacity for combining with a fixed number of atoms of another element—for example, hydrogen can bond with only one other element, and is called monovalent.



Verbs can be divided into classes based on their valency (how many arguments or ‘valents’ they can take). In some languages, these classes may have distinctive morphosyntactic characteristics, such as unique case marking patterns, or restrictions on tense/aspect/modality marking.

Answer 4

Valency refers to the number of atoms present in that.

eg:- Valency of

Hydrogen(H) is 1 because it contains only 1 atom

Oxygen(O)is 2 because it contains 2 atoms.

Answer 5

Valency is the 'combining power' of a substance. In other words, it is how much something will react before stopping. :)

Answer 6

Valency -> a property of atoms or radicals; their combining power given in terms of the number of hydrogen atoms ( or the equivalent)



-> the phenomenon of forming chemical bonds.
