Answer:
RbI and SrO
Step-by-step explanation:
Ionic Compounds are compounds formed with metallic and non-metallic ions.
For the compounds we have:
N - Non-Metal
H - Non-Metal
Rb - Metal
I - Non-Metal
S - Non-Metal
Cl - Non-Metal
Sr - Metal
NH3, SO2, ICl and NH4Cl we have non-metallic ions bounding with non-metallic ions.
RbI and SrO we have metallic ions bounding with non-metallic ions, that are ionic compounds.
