It is to be noted that every ion is larger in size than the corresponding atom. Oxidation State: The characteristic electronic configuration of the halogens is ns2 np5. WebHalogen atoms readily gain one electron to become negatively charged ions; these ions are called halide ions and have a charge of 1-. Halide ions can lose this extra electron and become halogen atoms again. If this happens, the ions are being oxidised, as they are losing an electron. how many words out of these letters
