Which element would have a full outer shell of electrons if it gained three electrons?
Vsevolod [243]

Answer:

Octet Rule is defined as the chemical rule in which atoms tend to form bonds in such a way that it completes its valence shell or tend to achieve the configuration of a noble gas.

Explanation:

The lithium is chemical element, which has atomic number 3. It has one valence electron in its outermost shell, therefore, it will require 7 more electrons to complete its octet.

The element nitrogen has the atomic number 7, such that it has 5 valence electrons in its outer most shell. Therefore, it will require 3 more electrons to complete its octet.

The noble gas Argon have complete octet, such that it does not require any electrons to complete its octet. the gas is inert and non-reactive.

The chemical element Boron has atomic number 5, such that it has three electrons in its outer most shell. Therefore, it will require 5 more electrons to complete its octet.

Hence, the correct option is Nitrogen.
