Question

complete the sentence using ide, ate or ic. to determine the name of an anion, you take the name of it’s element and replace the end with -

Explanation:

In chemistry (a subfield of Natural Science), when naming simple anions (negatively charged ions) formed from a single element, we take the element's name and replace the ending with -ide. For example, chlorine becomes chloride, oxygen becomes oxide. "ate" is used for polyatomic anions with more oxygen atoms in some cases, and "ic" is related to naming acids or cations in some naming conventions, not for simple anions. So the correct suffix here is ide.

Answer:

ide
