Answer
a) NaBr - Sodium Bromide
b) $Rb_{2}O$ - Rubidium Oxide
c) CaS - Calcium sulfide
d) $AlI_{3}$ - Aluminum iodide
e) Strontium fluoride - $SrF_{2}$
f) Aluminum selenide - $Al_{2}Se_{3}$
g) Potassium nitride - $K_{3}N$
h) Magnesium phosphide - $Mg_{3}P_{2}$
Work Step by Step
a) Sodium ($Na^{+}$ ) + Bromine $Br^{-}$ $\longrightarrow$ NaBr
b) Rubidium ($Rb^{+}$ ) + Oxide ($O^{2-}$ ) $\longrightarrow$ $Rb_{2}O$
c) Calcium ($Ca^{2+}$ ) + Sulfide ($S^{2-}$ ) $\longrightarrow$ CaS
d) Aluminum ($Al^{3+}$ ) + Iodide ($I^{-}$ ) $\longrightarrow$ $AlI_{3}$
e) Strontium ($Sr^{2+}$ ) + Floride($F^{-}$ ) $\longrightarrow$ $SrF_{2}$
f) Aluminum ($Al^{3+}$ ) + Selenide ($Se^{2-}$ ) $\longrightarrow$ $Al_{2}Se_{3}$
g) Potassium ($K^{+}$ ) + Nitride($N^{3-}$ ) $\longrightarrow$ $K_{3}N$
h) Magnesium ($Mg^{2+}$ ) + Phosphide ($P^{3-}$ ) $\longrightarrow$ $Mg_{3}P_{2}$
