Answer:
Explanation: Calcium, Ca , is located in group 2 of the periodic table, which means that is has two electrons on its outermost shell. In order to have a complete octet, calcium must lose these two outermost electrons, also called valence electrons. Calcium will react with nonmetals to form ionic compounds.
