Correct Answers: B and C
You need to find a pair that has a metal and a nonmetal.
It's very important to know whether elements are metals or nonmetals. Often, the TEAS will only give you the element symbols, and you need to figure out if the element is a metal or nonmetal.
In choice B, Na (sodium) is metal and F (fluorine) is a nonmetal. In choice C, Ba (barium) is a metal, and Cl (chlorine) is a nonmetal.
