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.
