Either zero or minus one.
Halogens are the most stable in their group because they have a full outer shell of electrons when they gain one electron to form a 1- charge. This full outer shell allows halogens to achieve the electron configuration of a noble gas, making them more stable.
Phosphite has an ionic charge of -3.
Halogens like chlorine, fluorine, and iodine have seven electrons in their outer shell, making them one electron short of a stable octet. By gaining an electron through ionic bonding with metals, halogens achieve a full outer shell and become more stable. This allows them to form ionic compounds with metals.
The ionic charge of stannous (tin) is typically +2.
The ionic charge of bromate ion (BrO3-) is -1.

When halogens form ions, they are called halide ions. These types of ions have a negative charge due to gaining electrons.
Phosphite has an ionic charge of -3.
Alkali metals and halogens.
I think what you are asking is about is which group on the periodic table has elements with an oxidation number of -1 in most ionic compounds. That is the 17th group - the halogens.
-1

The halogen (group 17/VIIA) atoms form ions with a 1- charge when undergoing ionic bonding. An atom gains one electron from a metallic element, resulting in the metal developing an ion with a 1+ charge. The electrostatic attraction between the oppositely charged ions forms the ionic bond.
Alkali metals , alkaline earth metals and halogens are most important ionic compound former .
The ionic charge of stannous (tin) is typically +2.
The ionic charge of bromate ion (BrO3-) is -1.
The products of the reactions are ionic salts.
