Answer: Both the -ate and -ite polyatomic ions are negatively charged and have the element oxygen in them.
Step-by-step explanation:
These ions are part of a group of anions known as oxyanions. The -ate and -ite suffixes are used to denote these oxyanions. For example, the nitrate ion (NO₃⁻) and the nitrite ion (NO₂⁻) are both oxyanions of nitrogen. The -ate suffix is used for the most common oxyanions of an element, while the -ite suffix is used for oxyanions that have the same charge but with one less atom of oxygen
