Answer:
The correct answer is option d. a polyatomic anion.
Explanation:
Hello! Let's solve this!
The ending "ate" or "ite" indicates that there is a negative polyatomic ion (polyatomic anion). This means that the termination of the name will indicate the valence number of the element, if the number used is the highest or the lowest.
An example is:
CO-3: is the carbonate ion
SO-4: is the sulfate ion
We conclude that the correct answer is option d. a polyatomic anion.
An ate or ite suffix at the end of a compound name usually indicates that the compound is a polyatomic anions.
Polyatomic ion:
The ions that contain more than one type of atom. Most of polyatomic ions are anions that are named with suffix -ate or -ite.
For examples-
[tex]\bold {CO_3^-^2}[/tex]- Carbonate ion, end with -ate.
[tex]\bold {SO_3^-^2}[/tex] Sulfite ion, end with -ite.
Therefore, an ate or ite suffix at the end of a compound name usually indicates that the compound is a polyatomic anions.
