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


X: 1s22s22p63s1

Y: 1s22s1


Which statement is most likely correct about the two elements?

A. They will react because X can give up one electron and Y needs 1 electron to become stable.
B. They will react because X and Y can share a pair of electrons to become stable.
C. They will not react because both have a complete outermost shell and are stable.
D. They will not react because both have to give up one electron to become stable.
