2. what's the relationship between the name of an atom and the name of its corresponding (monoatomic) cation ?

3. what's the relationship between the name of an atom and the name of its corresponding (monoatomic) anion ?

4. filled in the blanks.

ionic compounds are composed of (i) _____, which maybe a(n) ____ or a(n) ________, or (ii) a(n) _____ and a(n) ____, which is separated by a "diagonal" in your periodic table handout.

using the terms (there are extraneous terms)

atom(s) compound ion(s) nonmetal
cation metal molecule anion

5. fill-in the below table in regards to various ionic compounds.

chemical formula chemical name
NaCl  
KOH  
Ca(OH)2  
(NH4)2S  

a. based on your preceding answers, generalize the relationship between the chemical formula of an ionic compound and its chemical name; e.g. chemical name of an ionic compound = _____________________.

b. identify the cation and anion, by its chemical symbol and its name, in the above table.

c. identify the number of each cation and anion in one "molecule" of the ionic compound in the above table.

6. Some cations have multiple possible charges; e.g. Fe 2+ versus Fe 3+; fill-in the below table in regards to various ionic compounds, where your answer accounts for the different charge of the cation - you'll have to determine how to accomplish this goal.

chemical formula chemical name
FeCl2  
FeCl3  
CuOH  
SnS2  

a. based on your preceding answers, generalize the relationship between the chemical formula of an ionic compound and its chemical name; e.g. chemical name of an ionic compound = _____________________, which is slightly different from your answer in question 5. that is, what is the difference between your answers in the tables for question 5 versus 6 ?

7. what is the charge of an ionic compound ? based on your answer, what is the relationship between the (net / total) charge of a cation and anion in an ionic compound ?

8. in the below periodic table, oxidation state refers to "charge" of the ion [source: https://sciencenotes.org/wp-content/uploads/2014/05/PeriodicTableOxidation.png]
