What element has atoms that can form halide ions?

Atoms that can form halide ions are typically found among the halogens, which are elements in group 17 of the periodic table. This group includes fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). Halogens easily gain one electron to achieve a full valence shell, similar to that of noble gases, becoming negatively charged halide ions (such as F-, Cl-, Br-, and I-). These ions commonly form ionic compounds with metals. However, some elements like mercury, elements of group 13 with an oxidation state of 3+, tin(IV), and lead(IV) create covalent binary halides. Halides of metals can vary from ionic to covalent, while halides of nonmetals are typically covalent. Moreover, interhalogens occur when two or more different halogens combine.

The elements that form halide ions are found in Group 17 of the periodic table and are known as halogens, including fluorine, chlorine, bromine, iodine, and astatine. They achieve halide ions by gaining one electron, resulting in negatively charged ions like Cl⁻ or Br⁻. These ions are critical in forming various ionic and covalent compounds.
