Question
- A. Covalent molecular compounds
- B. Ionic salts containing metal ions
- C. Giant metallic lattices
- D. Noble-gas compounds with full outer shells
Answer
Covalent molecular compounds
Explanation
The correct option is "Covalent molecular compounds". Halogens reacting with non-metals form covalent compounds. Halogens reacting with metals form ionic salts, so this keeps the metal/non-metal boundary clear.
Common mistake
Misunderstanding Non-Metal Reactions
Students often think that halogens only form ionic compounds when reacting with non-metals.
Emphasize that halogens can also form covalent compounds with non-metals, as they share electrons.
