question\nwhich pair of elements will not form an ionic compound?\nselect the correct answer below:\no li and f\no na and o\no c and br\no ca and cl

Answer

Answer:

C. C and Br

Explanation:

Step1: Recall ionic compound formation

Ionic compounds form between metals and non - metals.

Step2: Analyze each pair

Li (metal) and F (non - metal) can form an ionic compound (LiF). Na (metal) and O (non - metal) can form an ionic compound (e.g., Na₂O). Ca (metal) and Cl (non - metal) can form an ionic compound (CaCl₂). C and Br are both non - metals. Non - metals form covalent compounds through sharing of electrons, not ionic compounds.
