Fluorine is in Group 17 (Group 7A) of the periodic table, and it typically gains one electron to achieve a stable octet configuration. Therefore, its ion is likely to have a charge of 1-.

potassium, Group IA

calcium, Group IIA
iodine, Group VIIA
neon, Group VIIIA

To determine which of the following is a negatively charged ion (anion), we will need to look at the naming rules for ions.

In general, the naming of monatomic ions follows a simple pattern. For negatively charged ions, the name typically ends in "-ide."

Now let's analyze the options provided:

1. Chlorate: This name does not end in "-ide," so it is not a negatively charged ion.
2. Chloride: This name does end in "-ide," indicating that it is a negatively charged ion.
3. Chlorine: This is not the name of an ion, but rather the name of a chemical element.
4. Chlorite: This name does not end in "-ide," so it is not a negatively charged ion.

Therefore, the correct answer is chloride, which is a negatively charged ion.
