would alcl₃ be classified as ionic or covalent?
covalent
ionic

Explanation:

For \(SF_4\):

• \(SF_4\) is sulfur tetrafluoride. Sulfur (\(S\)) and fluorine (\(F\)) are both non - metals.
• Non - metals tend to form covalent bonds by sharing electrons.

For \(AlCl_3\):

• Although aluminum (\(Al\)) is a metal and chlorine (\(Cl\)) is a non - metal, the electronegativity difference between \(Al\) and \(Cl\) is not large enough to form a fully ionic bond.
• In \(AlCl_3\), there is significant covalent character due to the relatively high charge density of \(Al^{3 +}\) which polarizes the \(Cl^{-}\) ions.

Answer:

For \(SF_4\): B. covalent
For \(AlCl_3\): A. covalent
