Question

the following element u to z 3u,6v,9w,14x,18y,20z .state the electronic configuration of each and state whether they are metals,non metals or inert gases.

Answer 1

Answer:

Explanation:Zero group of Mendeleev's periodic table or the group 18 of long form of periodic table is comprised of six elements and these eleements are called as inert gases as trhese elements do not react (inert) with other elements due to their octet outer electronic configaration which is stable configaration. The electronic configuration is listed in the following table.
