Interpretation:
The formulas of aluminium bromite, potassium dichromate (dichromate ion, Cr2O72-), barium hydrogen phosphate, rubidium selenate (rubidium, Z = 37; selenium, Z = 34) is to be stated.
Concept introduction:
The elements are found as single atom particles in the universe. Few elements form monoatomic ions having different charges. To differentiate the two ions, size of the charge of ions is included when naming the ion. Conversely, for group 1A, 2A, 5A-7A elements the charge is not included while naming the ion. In common, the charge is given in the name of an ion only when the ions of an element display more than one charge which is common
