Answer 1

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).
