Define Valency?????
Answers
➢ Valency
- Valencey (Valence) is a property of an atom of an element combined with atoms of other elements {that is, a compound}.
Generally, the valencey is equal to the number of gain and loss electrons of each atom in the compound, that is, the number of gain and loss electrons when the element can reach a stable structure, which is often determined by the electron arrangement of the element, mainly the outermost electron Arrangement, of course, may also involve a metastable structure composed of sublayers that can be reached by the secondary outer layer.

- Middle school
It is the number of electrons lost or gained by atoms in a substance or the number of offsets of common electron pairs .
- The valence represents the number of atoms gaining and losing electrons when atoms combine with each other.
- Valency is also a property exhibited by elements when they form compounds.
- Valence means
The apparent charge number of an atom of an element. This charge number is obtained by assuming that the electron in each chemical bond is assigned to a more electronegative atom.

It is the combining capacity of an element
