Answer:
Y and group number 17
Explanation:
Iodine is the chemical element of symbol I and atomic number 53, belonging to group 17 or of the halogens, in the periodic table. It is an element that we can find both in its molecular form, and in a diatomic way. In addition, iodine is a trace element and is used in the field of medicine and photography, as well as in some cases it is used as a dye. In the field of chemistry, iodine is the least reactive halogen element. Like the rest of the halogens, iodine also forms diatomic molecules, in this case the diiodine (I2).
Iodine is part of numerous compounds, despite being the element with the lowest reactivity in its group. It has some characteristics of metals, and their oxidation states are -1, + 1, + 3, + 5, + 7.
Despite its use, it is the halogen as a minor abundance, with only 0.14 ppm concentration in the earth's crust, however, in seawater its abundance is exactly 0.052 ppm.
