AA pure metal
BA noble gas
CA halogen
DA metalloid
Answer & Solution
Correct answer: A. A pure metal
1. The two partners in an ionic bond play opposite roles.
2. Binary ionic compounds are composed of just two elements.
3. One is a metal, which forms the cations, and the other a nonmetal, which forms the anions.
4. Noble gases are stable already and rarely form such compounds.
