a.Tin (II) Chloride
b. Iron (II) Oxide
c. Copper (I) Sulfide
d. Copper (II) Sulfide
e. Cadmium Bromide
f. Mercury (II) Chloride
Work Step by Step
STEP 1: writing the ions.
Using the Periodic Table 6.2 on page 187 we will find which atoms lose valence electrons and which ones gain valence atoms. Also, it shows the number of electrons lost in groups 1A,2A,3A and gained in groups 5A,6A,7A.
STEP 2: put a roman number after the metals with variable charges.
Transition metals (except zinc, cadmium, silver) and groups 4A and 5A can form 2 or more different ions, meaning that they have a variable charge. To differentiate the ions formed by the same element, put the Roman number equivalent to their charge, in parentheses, after the element name.
STEP 3: writing the name of the compounds.
To name an ionic formula formed by metals with variable charges, you have to put the Roman numeral between the metal and the first syllable of the nonmetal followed by 'ide'.
