Question

fill in the name and empirical formula of each ionic compound that could be formed from the ions in this table. some ionic compounds cation anion empirical formula name of compound $na^{+}$ $br^{-}$ $na^{+}$ $cl^{-}$ $na^{+}$ $i^{-}$ $na^{+}$ $f^{-}$

Explanation:

Step1: Combine ions

For ionic compounds, the cation and anion combine in a ratio such that the overall charge is zero. Sodium ion ($Na^+$) has a +1 charge and the halide anions ($Br^-$, $Cl^-$, $I^-$, $F^-$) have a - 1 charge. So, they combine in a 1:1 ratio.

Step2: Name the compounds

The naming of ionic compounds with a single - charge cation (like $Na^+$) and a single - charge anion (like halide ions) follows the rule of naming the cation first and then the anion with the ending changed to - ide.

Answer:

cation	anion	empirical formula	name of compound
$Na^+$	$Cl^-$	$NaCl$	sodium chloride
$Na^+$	$I^-$	$NaI$	sodium iodide
$Na^+$	$F^-$	$NaF$	sodium fluoride
