Question

substance,element 1 symbol; metal/nonmetal,element 2 symbol; metal/nonmetal,ionic/covalent,chemical name

1. mgs,mg: metal,s: nonmetal,ionic (i),magnesium sulfide
2. al₂o₃,al;metal,o;nonmetal,ionic,aluminum oxide
3. p₃o₆,p;nonmetal
4. ca₃n₂,ca;metal
5. n₂o₅,n;nonmetal
6. so₂,s;nonmetal
7. k₃p

Explanation:

Step1: Identify bonding type

For $P_3O_6$, since both $P$ (phosphorus) and $O$ (oxygen) are non - metals, the bond is covalent.

Step2: Name the compound

The name of $P_3O_6$ is Triphosphorus Hexoxide.

Step3: For $Ca_3N_2$

Calcium ($Ca$) is a metal and nitrogen ($N$) is a non - metal, so the bond is ionic. The name is Calcium Nitride.

Step4: For $N_2O_5$

Both nitrogen ($N$) and oxygen ($O$) are non - metals, so the bond is covalent. The name is Dinitrogen Pentoxide.

Step5: For $SO_2$

Sulfur ($S$) and oxygen ($O$) are non - metals, so the bond is covalent. The name is Sulfur Dioxide.

Step6: For $K_3P$

Potassium ($K$) is a metal and phosphorus ($P$) is a non - metal, so the bond is ionic. The name is Potassium Phosphide.
