Rubidium (an alkali metal) does not form compounds or ionic bonds with calcium (an alkaline earth metal). The two each form compounds with several of the same elements (e.g. chloride, carbonate, nitrate).
Yes. As an alkali metal, rubidium forms almost exclusively ionic compounds.
Rubidium and calcium are chemical elements not compounds.
Yes.
Rubidium iodide is an ionic compound.

Rubidium hydroxide is an ionic compound.
Rubidium by itself is neither ionic nor covalent. When it forms bonds with other elements, it forms ionic bonds.

Rubidium hydroxide is an ionic compound.
If you think to rubidium bromide (RbBr) this compound is ionic.
Rubidium by itself is neither ionic nor covalent. When it forms bonds with other elements, it forms ionic bonds.
Calcium chloride is an ionic compound.
RbCN is rubidium cyanide.
Ionic.
Yes, the bonds between rubidium ions and carbonate ions in rubidium carbonate are ionic bonds.
