write a formula for the compound that forms between rubidium and each of the

Carbonate: Rb2CO3
Phosphate: Rb3PO4
Hydrogen Phosphate: Rb2HPO4
Acetate: RbC2H3O2
each number is written as subscript
Rubidium (Rb) gains an electron when bonded ionic, becoming negatively charged.
Carbonate, CO3, loses an electron
Phosphate, PO4, will lose three electrons. B/c Rb gains one electron, two other Rb atoms each gain one
With Hydrogen Phosphate, HPO4one of the three electrons is bonded with hydrogen, so it will lose only two electrons
Acetate, C2H3O2, loses only one electron
