Is iodine a metal, metalloid, or nonmetal? - Chemistry Q&A

Iodine is a metalloid. Metalloid elements have one or more allotropes with properties intermediate between those of a metal and a nonmetal. Metals are lustrous, ductile, and conductive of heat and electricity. Metalloids may be semiconductors , like silicon, germanium, arsenic, and carbon (graphite). They may be lustrous, but brittle, like

Which of the following is a lustrous non - metal?

Click here👆to get an answer to your question Which of the following is a lustrous non - metal? Non-metals do not have lustre. They do not reflect light from their surface (exception - graphite, diamond and iodine). Non-metals have a dull appearance.
