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

Explanation:

Step1: Determine bonding type for $P_3O_6$

Non - metals form covalent bonds. Since both P and O are non - metals, it is covalent.

Step2: Name the compound

The prefix for 3 is "tri -" and for 6 is "hexa -". The name is Triphosphorus Hexoxide.

Step3: Determine bonding type for $Ca_3N_2$

A metal (Ca) and a non - metal (N) form an ionic bond.

Step4: Name the compound

It is Calcium Nitride.

Step5: Determine bonding type for $N_2O_5$

Both N and O are non - metals, so it is covalent.

Step6: Name the compound

The prefix for 2 is "di -" and for 5 is "penta -". The name is Dinitrogen Pentoxide.

Step7: Determine bonding type for $SO_2$

Both S and O are non - metals, so it is covalent.

Step8: Name the compound

It is Sulfur Dioxide.

Step9: Determine bonding type for $K_3P$

A metal (K) and a non - metal (P) form an ionic bond.

Step10: Name the compound

It is Potassium Phosphide.
