Question

based on the chemical formula, what type of compound is sodium nitrate (nano₃)? why?
there is not enough information provided to determine the type of bond for sodium nitrate.
sodium nitrate is an ionic compound because it is composed of a positive and negative ion (metal and nonmetal).). a metallic compound would have multiple metals bonded to each other.
sodium nitrate is a covalent compound because it contains multiple nonmetals, nitrogen and oxygen. a metallic compound would have multiple metals bonded to each other.
sodium nitrate is a metallic compound because it is composed of a mixture with metal ions. an ionic compound would contain only two elements, a metal and nonmetal.

Explanation:

Ionic compounds are formed from positive and negative ions. Sodium (\(Na^+\)) is a metal (forms positive ion) and nitrate (\(NO_3^-\)) is a poly - atomic ion (negative ion, composed of non - metals nitrogen and oxygen). Metallic compounds involve metal - metal bonding. Covalent compounds are formed between non - metals (but sodium nitrate has a metal ion). The formula \(NaNO_3\) shows it has a metal ion (\(Na^+\)) and a non - metal based poly - atomic ion (\(NO_3^-\)).

Answer:

Sodium nitrate is an ionic compound because it is composed of a positive and negative ion (metal and nonmetal).). A metallic compound would have multiple metals bonded to each other.
