Explanation:

Step1: Identify cations and anions

For ionic compounds, we identify the positive - charged cation and negative - charged anion. For example, in $Ag_2S$, the cation is $Ag^+$ (silver ion) and the anion is $S^{2 - }$ (sulfide ion).

Step2: Name the compound

Name the cation first, then the anion. For transition metals, we need to indicate the oxidation state in Roman numerals if there are multiple possible oxidation states.

1. $Ag_2S$: Cations are $2Ag^+$, anion is $S^{2 - }$. Name: Silver sulfide
2. $ZnO$: Cation is $Zn^{2+}$, anion is $O^{2 - }$. Name: Zinc oxide
3. $CuF$: Cation is $Cu^+$ (copper(I) ion), anion is $F^-$ (fluoride ion). Name: Copper(I) fluoride
4. $CuBr_2$: Cation is $Cu^{2+}$ (copper(II) ion), anion is $Br^-$ (bromide ion). Name: Copper(II) bromide
5. $MnCl_2$: Cation is $Mn^{2+}$ (manganese(II) ion), anion is $Cl^-$ (chloride ion). Name: Manganese(II) chloride
6. $SnBr_2$: Cation is $Sn^{2+}$ (tin(II) ion), anion is $Br^-$ (bromide ion). Name: Tin(II) bromide
7. $Rb_2O$: Cations are $2Rb^+$, anion is $O^{2 - }$. Name: Rubidium oxide
8. $PbF_4$: Cation is $Pb^{4+}$ (lead(IV) ion), anion is $F^-$ (fluoride ion). Name: Lead(IV) fluoride
9. $Ga_2O_3$: Cations are $2Ga^{3+}$, anion is $3O^{2 - }$. Name: Gallium oxide
10. $CsCl$: Cation is $Cs^+$, anion is $Cl^-$. Name: Cesium chloride
11. $V_2O_5$: Cation is $V^{5+}$ (vanadium(V) ion), anion is $O^{2 - }$. Name: Vanadium(V) oxide
12. $Mg_3N_2$: Cations are $3Mg^{2+}$, anion is $2N^{3 - }$. Name: Magnesium nitride
13. $Hg_2O$: Cation is $Hg_2^{2+}$ (mercury(I) ion), anion is $O^{2 - }$. Name: Mercury(I) oxide
14. $HgO$: Cation is $Hg^{2+}$ (mercury(II) ion), anion is $O^{2 - }$. Name: Mercury(II) oxide
