Question

Which two elements will most likely form an ionic bond? (Click on the periodic table icon to view these elements) krypton and lithium magnesium and bromine calcium and potassium iodine and chlorine

Answer 1

Answer:

Magnesium and Bromine

Explanation:

I just took the test, and Magnesium has 7 electrons and Bromine has 2 valance electrons making the transfer a lot easier. In the first choice, Krypton already has 8 valance electrons therefore it cannot transfer or accept any more which rules it out as a possible answer. Calcium has 2 valance electrons and Potassium has 1 meaning it couldn't make a full shell of 8 and cannot make a ionic bond. Iodine has 7 electrons as well as Chlorine which wouldn't be the answer because it would have more than 8 valance electrons.
