Its Rb because its the only metal listed and ionic compounds are formed as a result of a metal bonding with a nonmetal which is the chlorine.
Rb because if you the subtract the electronegativities:
(Cl) 3.2 - (Rb) .8 = 2.4 which is more than 2.0 making it ionic.
Zinc sulphide is actually an ionic compound.
The smallest whole number ratio of elements in an ionic or covalent compound is known as the empirical formula. It represents the simplest ratio of atoms of each element in a compound.
First, Ag is an element and not a compound at this form. Its name is silver
The chemical formula of ammonia is NH3; the solution in water is basic - NH4OH. The molecule NH3 is polar. Ammonia is not an element but a chemical compound.
In Chemthink Ionic Formulas, X represents an unknown element that you need to identify by determining the charge of the cation and anion in the ionic compound. By balancing the charges using X as the unknown element, you can deduce the correct formula for the compound.

Ca (calcium) is an element, not a compound. and it can only form ionic compounds.
Iron is not a compound, it is a metallic element.
No. It is an ionic compound.
The element that forms the cation (positive ion) comes first in the formula for an ionic compound.
Phosphorus is a chemical element, not a compound.
Fluorine is molecular, but it is an element, not a compound.
Ferric chloride is an ionic compound (and is classified as a salt).
