#### Answer

a) CsF - Cesium fluoride b) $Li_{3}N$ - Lithium nitride c) $Ag_{2}S$ - Silver (I) sulfide d) $MnO_{2}$ - Manganese (IV) dioxide e) $TiO_{2}$ - Titanium (IV) dioxide f) $Sr_{3}P_{2}$ - Strontium phosphide

#### Work Step by Step

a) Cesium ($Cs^{+}$) + Fluoride ($F^{-}$) $\longrightarrow$ CsF b) Lithium ($Li^{+}$) + Nitride ($N^{3-}$) $\longrightarrow$ $Li_{3}N$ c) Silver ($Ag^{+}$) + Sulphide ($S^{2-}$) $\longrightarrow$ $Ag_{2}S$ d) Manganese ($Mn^{4+}$) + Oxide($O^{2-}$) $\longrightarrow$ $MnO_{2}$ e) Titanium ($Ti^{4+}$) + Oxide ($O^{2-}$) $\longrightarrow$ $TiO_{2}$ f) Strontium ($Sr^{2+}$) + Phosphide ($P^{3-}$) $\longrightarrow$ $Sr_{3}P_{2}$
