Question

Question 8
Where would you locate the element with electronic configuration 2,8 in the Modern Periodic Table?

(a) Group 8
(b) Group 2
(c) Group 18
(d) Group 10

Answer 1

Option (c) is correct.
The noble gases are in Group 18 (8A). They are helium, neon, argon, krypton, xenon, and radon. They were once called inert gases because they were thought to be completely inert—unable to form compounds. Their outermost shell is filled with 8 electrons and so they do not gain or lose electrons.
