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.
