Question

1. write the formula for the following binary ionic compounds.

a. calcium chloride
b. sodium fluoride
c. magnesium oxide
d. aluminum fluoride
e. aluminum sulfide
f. lithium oxide
g. lead(iv) oxide
h. copper(ii) fluoride
i. sodium phosphide
j. lithium nitride

1. write formulas for the following ionic compounds containing polyatomic ions.

a. barium sulfite
b. ammonium nitrite
c. lithium sulfate
d. sodium acetate
e. calcium carbonate
f. barium hydroxide
g. calcium chlorate
h. magnesium chlorite

Explanation:

Step1: Determine ion charges

For binary ionic compounds, identify the charges of the metal and non - metal ions. For compounds with polyatomic ions, know the charge of the polyatomic ion and the metal ion.

Step2: Balance charges

Combine the ions in a ratio that makes the overall compound electrically neutral.
