Is Na2SO4 ionic or molecular?

Na2SO4 is an ionic compound. It consists of positively charged sodium ions (Na+) and negatively charged sulfate ions (SO4 2-), which are attracted to each other through ionic bonds.

Na2SO4 is an ionic compound. To determine if a compound is ionic or molecular, we need to consider the types of elements involved and the bonding pattern. In the case of Na2SO4, it contains a metal (sodium) and a nonmetal (sulfur) along with oxygen. Ionic compounds form when a metal transfers electrons to a nonmetal. In Na2SO4, sodium donates two electrons to sulfur to form a sodium ion (Na+) and a sulfate ion (SO42-). This transfer of electrons results in the formation of strong electrostatic attractions between the oppositely charged ions, making Na2SO4 an ionic compound.

To determine whether Na2SO4 is ionic or molecular, we need to consider the types of elements present in the compound and their bonding behavior.

In Na2SO4, we have sodium (Na) and sulfate (SO4) ions. Sodium is an alkali metal, which readily loses one electron to achieve a stable electron configuration, forming a cation with a +1 charge (Na+). Sulfate, on the other hand, is a polyatomic ion consisting of sulfur (S) and four oxygen (O) atoms. Sulfate carries a -2 charge (SO4^2-).

Since Na+ is a cation and SO4^2- is an anion, the compound Na2SO4 is considered ionic. In this case, the sodium cations are attracted to the sulfate anions through ionic bonds. Ionic compounds consist of charged particles held together by electrostatic forces, and they typically form crystals with high melting points.

It is important to note that in the solid state, Na2SO4 exists as a crystal lattice where the sodium cations and sulfate anions are arranged in a repeating pattern. However, when Na2SO4 is dissolved in water, it dissociates into its constituent ions, Na+ and SO4^2-, forming an ionic solution.
