On the periodic table, where are the noble gases located?
a. in the center
b. on the left side
c. in the upper right corner
d. on the far right side

D. on the far right side. The group 8A, whose elements are He, Ne, Ar, Kr, Xe and Rn.

Explanation:

The location of any element in the periodic table is related to its electron configuration. All the noble gases have something in common: their s and p subshells are full. Which means they have no space for sharing electrons or acquiring more. This fact can be illustrated by showing the spdf of Ne:

That's why they're so stable.

According to the Lewis theory, all of them have eight electrons in their outer energy level (all except for helium, which has only two electrons). That is, all of them obey the octect rule.  

i'm wiling to try and you : )
