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 :

Group 18 in the modern periodic table has noble gases (inert gases). Helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe) and radon (Rn) are present in group 18. The members of the group have eight electrons in their outermost orbit (except helium which has two electrons). Thus, they have a stable electronic configuration. These gases are chemically unreactive, that is, they don’t react with other elements to form compounds.
