Response

To complete the table for simple binary ionic compounds, we use the rules of ionic compound formation (criss - cross method for charges):

1. Sodium bromide
  • Sodium ($\text{Na}$) has a charge of $+ 1$ ($\text{Na}^+$), and bromide ($\text{Br}$) has a charge of $-1$ ($\text{Br}^-$).
  • Using the criss - cross method, the formula is $\text{NaBr}$.
2. Calcium chloride
  • Calcium ($\text{Ca}$) has a charge of $+2$ ($\text{Ca}^{2 + }$), and chloride ($\text{Cl}$) has a charge of $-1$ ($\text{Cl}^-$).
  • Cross - multiplying the charges, we get $1$ $\text{Ca}$ and $2$ $\text{Cl}$, so the formula is $\text{CaCl}_2$.
3. Magnesium sulfide
  • Magnesium ($\text{Mg}$) has a charge of $+2$ ($\text{Mg}^{2+}$), and sulfide ($\text{S}$) has a charge of $-2$ ($\text{S}^{2 - }$).
  • The formula is $\text{MgS}$ (since the charges cancel out: $+2$ and $-2$).
4. Aluminum oxide
  • Aluminum ($\text{Al}$) has a charge of $+3$ ($\text{Al}^{3+}$), and oxide ($\text{O}$) has a charge of $-2$ ($\text{O}^{2 - }$).
  • Cross - multiplying, we have $2$ $\text{Al}$ and $3$ $\text{O}$, so the formula is $\text{Al}_2\text{O}_3$.
5. Lithium phosphide
  • Lithium ($\text{Li}$) has a charge of $+1$ ($\text{Li}^+$), and phosphide ($\text{P}$) has a charge of $-3$ ($\text{P}^{3 - }$).
  • Cross - multiplying, we get $3$ $\text{Li}$ and $1$ $\text{P}$, so the formula is $\text{Li}_3\text{P}$.
6. Cesium nitride
  • Cesium ($\text{Cs}$) has a charge of $+1$ ($\text{Cs}^+$), and nitride ($\text{N}$) has a charge of $-3$ ($\text{N}^{3 - }$).
  • Cross - multiplying, we have $3$ $\text{Cs}$ and $1$ $\text{N}$, so the formula is $\text{Cs}_3\text{N}$.
7. Potassium iodide
  • Potassium ($\text{K}$) has a charge of $+1$ ($\text{K}^+$), and iodide ($\text{I}$) has a charge of $-1$ ($\text{I}^-$).
  • The formula is $\text{KI}$.
8. Barium fluoride
  • Barium ($\text{Ba}$) has a charge of $+2$ ($\text{Ba}^{2+}$), and fluoride ($\text{F}$) has a charge of $-1$ ($\text{F}^-$).
  • Cross - multiplying, we get $1$ $\text{Ba}$ and $2$ $\text{F}$, so the formula is $\text{BaF}_2$.
9. Rubidium nitride
  • Rubidium ($\text{Rb}$) has a charge of $+1$ ($\text{Rb}^+$), and nitride ($\text{N}$) has a charge of $-3$ ($\text{N}^{3 - }$).
  • Cross - multiplying, we have $3$ $\text{Rb}$ and $1$ $\text{N}$, so the formula is $\text{Rb}_3\text{N}$.
10. Barium oxide
  • Barium ($\text{Ba}$) has a charge of $+2$ ($\text{Ba}^{2+}$), and oxide ($\text{O}$) has a charge of $-2$ ($\text{O}^{2 - }$).
  • The formula is $\text{BaO}$.
11. For formula $\text{K}_2\text{O}$
  • Potassium ($\text{K}$) has a charge of $+1$ ($\text{K}^+$), and oxide ($\text{O}$) has a charge of $-2$ ($\text{O}^{2 - }$).
  • The name is Potassium oxide.
12. For formula $\text{MgI}_2$
  • Magnesium ($\text{Mg}$) has a charge of $+2$ ($\text{Mg}^{2+}$), and iodide ($\text{I}$) has a charge of $-1$ ($\text{I}^-$).
  • The name is Magnesium iodide.
