Question

using the periodic table, what can you conclude about the classification of iodine? a iodine is a noble gas and has a full valence electron shell, is chemically non - reactive, colorless, odorless, and is a gas at room temperature. b iodine is a metal and is shiny, malleable, ductile, conducts heat and electricity, forms basic oxides, and forms cations in aqueous solution. c iodine is a nonmetal and is dull, brittle, poor conductor of heat and electricity, forms anions in aqueous solution, and is a solid at room temperature. d iodine is a metalloid and has properties of both metals and nonmetals - it appears lustrous, but is brittle and a poor conductor of heat and electricity.

Explanation:

Iodine is a non - metal. Non - metals are dull, brittle, and poor conductors of heat and electricity. They form anions in aqueous solutions. Iodine is a solid at room temperature.

Answer:

C. Iodine is a nonmetal and is dull, brittle, poor conductor of heat and electricity, forms anions in aqueous solution, and is a solid at room temperature.
