Question

complete the following table:
two polyatomic anions
name\tchemical formula
sulfate anion\t
\tno₃⁻

Explanation:

• Sulfate anion: It consists of one sulfur atom (\(S\)) and four oxygen atoms (\(O\)), with a charge of \(- 2\). The formula is determined by the combination of these atoms and the charge.
• \(NO_{3}^{-}\): The polyatomic ion \(NO_{3}^{-}\) is named nitrate anion. This is a common name in chemical nomenclature for this particular ion structure.

Answer:
