Answer
Explanation:
Step1: Recall ion - charge rules
For binary ionic compounds, we determine the formula based on the charges of the cation and anion to ensure the compound is neutral. For example, sodium ($Na^+$) has a + 1 charge and bromide ($Br^-$) has a - 1 charge, so the formula of sodium bromide is $NaBr$.
Step2: Identify cations and anions
For calcium chloride, calcium ($Ca^{2 + }$) has a + 2 charge and chloride ($Cl^-$) has a - 1 charge. To balance the charges, we need 2 chloride ions for each calcium ion, so the formula is $CaCl_2$.
Step3: Determine correct sub - scripts
For aluminum oxide, aluminum ($Al^{3+}$) has a + 3 charge and oxide ($O^{2 - }$) has a - 2 charge. The least - common multiple of 3 and 2 is 6. So we need 2 aluminum ions ($2\times3 = 6$) and 3 oxide ions ($3\times2=6$) to balance the charges, giving the formula $Al_2O_3$. ... (continue this process for all compounds)
