Explanation:

Step1: Recall bond - type rules

Ionic bonds form between a metal and a non - metal. Covalent bonds form between non - metals.

Step2: Analyze H₂O

Hydrogen (H) and oxygen (O) are non - metals. So the bond in H₂O is covalent. Elements: Hydrogen, Oxygen; Bond: Covalent

Step3: Analyze CH₄

Carbon (C) and hydrogen (H) are non - metals. So the bond in CH₄ is covalent. Elements: Carbon, Hydrogen; Bond: Covalent

Step4: Analyze HCl

Hydrogen (H) and chlorine (Cl) are non - metals. So the bond in HCl is covalent. Elements: Hydrogen, Chlorine; Bond: Covalent

Step5: Analyze P₂O₅

Phosphorus (P) and oxygen (O) are non - metals. So the bond in P₂O₅ is covalent. Elements: Phosphorus, Oxygen; Bond: Covalent

Step6: Analyze CO₂

Carbon (C) and oxygen (O) are non - metals. So the bond in CO₂ is covalent. Elements: Carbon, Oxygen; Bond: Covalent

Step7: Analyze NaF

Sodium (Na) is a metal and fluorine (F) is a non - metal. So the bond in NaF is ionic. Elements: Sodium, Fluorine; Bond: Ionic

Step8: Analyze MgO

Magnesium (Mg) is a metal and oxygen (O) is a non - metal. So the bond in MgO is ionic. Elements: Magnesium, Oxygen; Bond: Ionic

Step9: Analyze FeCl₃

Iron (Fe) is a metal and chlorine (Cl) is a non - metal. So the bond in FeCl₃ is ionic. Elements: Iron, Chlorine; Bond: Ionic

Step10: Analyze NaCl

Sodium (Na) is a metal and chlorine (Cl) is a non - metal. So the bond in NaCl is ionic. Elements: Sodium, Chlorine; Bond: Ionic

Step11: Analyze K₂O

Potassium (K) is a metal and oxygen (O) is a non - metal. So the bond in K₂O is ionic. Elements: Potassium, Oxygen; Bond: Ionic

Step12: Analyze SO₂

Sulfur (S) and oxygen (O) are non - metals. So the bond in SO₂ is covalent. Elements: Sulfur, Oxygen; Bond: Covalent

Step13: Analyze NO₂

Nitrogen (N) and oxygen (O) are non - metals. So the bond in NO₂ is covalent. Elements: Nitrogen, Oxygen; Bond: Covalent
