General Chemistry 1- Polyatomic Ions | Latest Update | 2024/2025 | 100% Correct What are polyatomic ions, and how do they differ from monatomic ions? Polyatomic ions are ions composed of two or more atoms covalently bonded together, carrying a net charge. They differ from monatomic ions, which consist of only a single atom with a charge. What is the charge and composition of the sulfate ion? The sulfate ion has a charge of -2 and is composed of one sulfur atom covalently bonded to ...
