. 2. distinguish between Octect and Duplet
Answers
Answer:
The key difference between octet and duplet is that octet is an atom or an ion having a maximum of eight electrons in the outermost shell while duplet is an atom having the maximum of two electrons in the outermost shell.

Answer:
What is an Octet?
An octet is an atom or an ion having eight electrons in the outermost shell of that atom. All noble gases except helium have eight electrons and are inert in nature. The electron configuration of a noble gas will always end as follows.
ns2 np6
For example, the electron configuration of Neon is 1s22s22p6 . Neon is an inert gas.
What is a Duplet?
Hydrogen atom and helium atom are the smallest elements in nature and have only one orbital around their nucleus. This orbital is called 1s orbital. This orbital can contain a maximum of two electrons. Hydrogen atom has one electron and helium has two electrons. Hence, helium is called a duplet. Helium has the maximum number of electrons that it can have; thus it is a stable element in nature. Therefore, Helium is also an inert gas. But hydrogen has only one electron and the only orbital it has is incomplete. Thus, hydrogen atom alone is very reactive.
All duplets have electron configuration ending .
