(D) identify the elements present in group II A or group 2
(E) some elements are not reacting with other elements
(i) identify the chemically unreactive metal
(ii) give reason for your above answer
i, w is the noble gas having atomic number 10 and configuration (2,8)
ii, X , y and z are the s block elements
they have 2,2 and 1 electrons in their outermost shell respectively
iii, atomic size decreases across the period and increases down the group
element z is having more atomic size.
