For $\boldsymbol{Al_2O_3}$:
Step1: Identify Element 1
Element 1 is Al (Aluminum). Aluminum is a metal.
Step2: Identify Element 2
Element 2 is O (Oxygen). Oxygen is a nonmetal.
Step3: Determine Bond Type
Compounds between metals and nonmetals are ionic. So, $Al_2O_3$ is ionic.
For $\boldsymbol{P_3O_6}$ (simplify to $\boldsymbol{P_2O_4}$ or keep as is, but analysis is same):
Step1: Identify Element 1
Element 1 is P (Phosphorus). Phosphorus is a nonmetal.
Step2: Identify Element 2
Element 2 is O (Oxygen). Oxygen is a nonmetal.
Step3: Determine Bond Type
Compounds between nonmetals are covalent. So, $P_3O_6$ is covalent.
For $\boldsymbol{Ca_3N_2}$:
Step1: Identify Element 1
Element 1 is Ca (Calcium). Calcium is a metal.
Step2: Identify Element 2
Element 2 is N (Nitrogen). Nitrogen is a nonmetal.
Step3: Determine Bond Type
Compounds between metals and nonmetals are ionic. So, $Ca_3N_2$ is ionic.
For $\boldsymbol{N_2O_5}$:
Step1: Identify Element 1
Element 1 is N (Nitrogen). Nitrogen is a nonmetal.
Step2: Identify Element 2
Element 2 is O (Oxygen). Oxygen is a nonmetal.
Step3: Determine Bond Type
Compounds between nonmetals are covalent. So, $N_2O_5$ is covalent.
For $\boldsymbol{SO_2}$:
Step1: Identify Element 1
Element 1 is S (Sulfur). Sulfur is a nonmetal.
Step2: Identify Element 2
Element 2 is O (Oxygen). Oxygen is a nonmetal.
Step3: Determine Bond Type
Compounds between nonmetals are covalent. So, $SO_2$ is covalent.
For $\boldsymbol{K_3P}$:
Step1: Identify Element 1
Element 1 is K (Potassium). Potassium is a metal.
Step2: Identify Element 2
Element 2 is P (Phosphorus). Phosphorus is a nonmetal.
Step3: Determine Bond Type
Compounds between metals and nonmetals are ionic. So, $K_3P$ is ionic.
