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

X: 1s22s22p6
Y: 1s22s22p63s23p6

Which statement is most likely correct about the two elements?

They will react because X can give up two electrons and Y needs two electrons to become stable.

They will react because X and Y can share two pairs of electrons to become stable.


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

They will not react because both will give up one electron to become stable.

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