1 answer

The element that has chemical properties most similar to iodine is selenium (Se). This is because iodine and selenium belong to the same group (Group 17 or Group VIIA), also known as the halogens. Halogens generally have similar chemical properties due to their high reactivity and ability to gain one electron to achieve a full outer electron shell.
