Element X 18 is noble gas with electronic configuration 2,8,8 and element Z 16 with electronic configuration 2,8,6 .
Element Z is more reactive than element X because element X is a noble gas which is chemically inert in nature due to complete outermost shell. Element Z can attain 2 electrons to fill its outermost shell.
