Question

The electron configurations of two unknown elements X and Y are shown.

Answer 1

 X: 1S²2S²2P⁶

Y: 1S²2S²2P⁶3S²3P⁶

The statement  which  is most likely   correct  about  the two elements  is

They  will  not react  because  both  have a complete outermost shell and are  stable.

 Explanation

  The  P orbital can   hold a maximum  of   6  electrons,therefore the 2P orbital for x  and  3P  orbital  for  Y   which are  outermost  subshell  are  fully filled .

This make   element Y and x  stable  since they  cannot  react either by gaining or losing electrons.

Answer 2

Answer: They will not react because both have a complete outermost shell and are stable.
