Why has the zero group been placed at the extreme right of the periodic table?
Answers
Answer:
they are least reactive elements,so they are discovered later than alkali metals etc ,so they are placed at the extreme right of the periodic table because they have stable electronic configuration and their configuration lies in between alkali metals and halogen family.
sis can I get your intro???

Answer:
The elements of the zero group includes the noble gases such as helium, neon, argon, krypton, xenon, and radon. They are placed in a separate group which is at the extreme right of the periodic table due to the unique property exhibited by them which are as follows:
1. All the elements of the zero group have complete octet or duplet(in case of helium), whereas this is incomplete in case of the elements of other groups
2. Due to complete octet or duplet, they form a stable configuration and have no tendency to either give or receive electrons
