Question

compounds can be classified as covalent or ionic by noting the location on the periodic table for each atom in the compound. select all the compounds that are ionic. sulfur dioxide sodium chloride carbon monoxide potassium bromide magnesium chloride

Explanation:

Ionic compounds form between metals (left/center of periodic table) and nonmetals (right side). Covalent compounds form between nonmetals.

• Sulfur dioxide: Both S and O are nonmetals (covalent).
• Sodium chloride: Na (metal) + Cl (nonmetal) (ionic).
• Carbon monoxide: Both C and O are nonmetals (covalent).
• Potassium bromide: K (metal) + Br (nonmetal) (ionic).
• Magnesium chloride: Mg (metal) + Cl (nonmetal) (ionic).

Answer:

☑ sodium chloride
☑ potassium bromide
☑ magnesium chloride
