X,y,z are three elements with respective atomic number of a,(a+2),(a-2) . X is an inert gas. So which one is most electronegative? And which element forms a basic oxide? Give name of the oxide.

inert gas is neon as it is the first inert gas in periodic table having atomic number 10.
a is neon so it doesn't undergo electronegativety as it shells are completed their octat.
(a+2)=12 atomic number of magnesium its electronic configuration will be 2,8,2 so they will show electronegativety
(a-2) = 8 atomic number of oxygen its electronic configuration will be 2,6 so they gain electron they don't show electronegativety.
since metal is magnesium and non metal is oxygen
since we know metals are basic in nature and non metals are acidic in nature.
so here magnesium will form magnesium oxide which is a base.
