Question

Is iodine a metal, metalloid, or nonmetal?

Answer 1

Iodine$\mathbf{\left(}\mathbf{I}\mathbf{\right)}$:

• Iodine may be classified as a metalloid.
• Lustrous is the property of metals which is shown by Iodine.
• Iodine shows metallic properties when forming bonds with Fluorine and Chlorine. e.g. ${\mathrm{IF}}_3,{\mathrm{IF}}_7,{\mathrm{ICl}}_3$
• When forming bonds with metals like Potassium and Sodium, Iodine shows the non-metallic properties.e.g. $\mathrm{KI},\mathrm{NaI}$ etc

Thus, Iodine can be classified as metalloid.
