Question

question #5 of 6
which of the following substances is most likely to be covalent?
kf
co₂
nabr
mgcl₂

Explanation:

Step1: Recall ionic - covalent compound rules

Ionic compounds form between metals and non - metals, while covalent compounds form between non - metals.

Step2: Analyze each option

KF is between metal (K) and non - metal (F), so it is ionic. NaBr is between metal (Na) and non - metal (Br), so it is ionic. MgCl₂ is between metal (Mg) and non - metal (Cl), so it is ionic. CO₂ is between non - metals (C and O), so it is covalent.

Answer:

CO₂
