$19.$ This activity focused on molecular $($covalent$)$ compounds, while an earlier activity addressed ionic compounds. Notice that the formulas for both types of compounds can look very similar, even though their names are quite different:

$\backslash$table$[[$Chemical Formula,Type of Compound$/$Bonding$,$Compound Name$],[Mg{F}_2,$Ionic,Magnesium fluoride$],[Cu{F}_2,$Ionic,Copper$($II$)$ fluoride$],[S{F}_2,$Molecular $($covalent$),$Sulfur difluoride$],[NaBr,$Ionic,Sodium bromide$],[AuBr,$Ionic,Gold$($I$)$ bromide$],[IBr,$Molecular $($covalent$),$Iodine monobromide$]]$

Identify two differences between the names or formulas for ionic compounds versus those for binary molecular compounds. Also identify two similarities.
