Strontium (Sr), which has the atomic number 38, is an alkaline earth metal. Elements in this group typically have a tendency to lose electrons during bonding to achieve a stable electron configuration, similar to that of noble gases.
Specifically, strontium has two electrons in its outermost shell (the 5s subshell), and it tends to lose those two electrons when it forms bonds, resulting in the formation of a positive ion (Sr²⁺).
Therefore, the correct response is:
It will give up electrons, forming a positive ion.
