Verified step by step guidance

Identify the central atom in the polyatomic ion. In this case, it is carbon (C).

Determine the number of oxygen atoms bonded to the central atom. Here, there are two oxygen atoms (O).

Examine the charge of the ion. The ion has a charge of 2-, which is indicated by the superscript.

Recall the naming conventions for polyatomic ions: -ate and -ite suffixes are commonly used. The -ite suffix is used for ions with fewer oxygen atoms than the -ate form.

Combine the central atom name with the appropriate suffix based on the number of oxygen atoms and the charge. Since there are two oxygen atoms and the charge is 2-, the correct name is 'carbonite'.
