I think the correct answer from the choices listed above is the third option. Calcium and bromine have formed a bond. Leading up to this, calcium gave up electrons. It was a positive ion. Giving up electrons would make an atom more positive. Hope this answers the question. Have a nice day.

Answer:

It was a positive ion.

Explanation

In CaBr, ionic bond is present. When one of the atom loses electrons and gets positive charges and other atom gains electrons and become negative. As a result of positive and nagative charges , a ionic bond formed.

As in this case, Ca loses electrons and become positive ion while on the other hand bromide gets the electrons and become negative ion.

Note:

Electropositive atoms always loose electrons Like Ca while electronegative atoms always gain elelctrons like Br.
