what is valency in terms of electronic theory
Answers
Answer:
The electronic theory of valency was originated by Kossel and Lewis (1916) independently and applied by Langmuir (1919). According to this theory, every element has a tendency to occupy inert electronic configuration of the nearest inert gas, because it is considered as the most stable configuration (stable octet).

ANSWER ⤵️
Electronic Structure Theory describes the motions of electrons in atoms or molecules. Roughly speaking, relativistic effects are not generally considered important for atoms with atomic number below about 25 (Mn). ...
Lewis proposed that a chemical bond forms by the interaction of two shared bonding electrons, with the representation of molecules as Lewis structures.
It states that every element has a tendency to attain electronic configuration of the nearest inert gas,as it is the most stable configuration called stable octet(8 electrons) or duplet(2 electrons) and the number of electrons it accepts or donates is its valency.
For example
Boron has electronic configuration 2,3; So it would like to accept 3 electrons to attain octet. So its valency would be +3
