Which non metal is a good conductor of electricity?

GraphiteGraphite is a non-metal and it is the only non-metal that can conduct electricity. You can find non-metals on the right side of the periodic table and graphite is the only non-metal that is a good conductor of electricity.

What Colour is iodine Vapour?

violetPolar solutions, such as aqueous solutions, are brown, reflecting the role of these solvents as Lewis bases; on the other hand, nonpolar solutions are violet, the color of iodine vapour.

Is iodine acidic or basic?

Is Potassium A iodine?

What is Potassium Iodide (KI)? KI (potassium iodide) is a salt of stable (not radioactive) iodine that can help block radioactive iodine from being absorbed by the thyroid gland, thus protecting this gland from radiation injury. The thyroid gland is the part of the body that is most sensitive to radioactive iodine.

What is iodine used for medically?

Iodine is taken by mouth to prevent and treat iodine deficiency and its consequences, including goiter and some thyroid disorders. It is also used for treating lumpy breasts (fibrocystic breast disease) and breast pain (mastalgia).

What is the most stable form of iodine?

iodateIt is shown that although iodate is the most stable form, iodide may exist as a metastable form in a basic solution. Molecular iodine may undergo disproportionation to form iodide and iodate.

Does iodine have a shiny surface?

Iodine is the only non metal having a shiny surface.

Why does graphite and iodine shine?

Because graphite and iodine have free electrons. When sunlight falls on such surface, free electrons getc vibrated and reflect light. Then it shines.

Why iodine is violet in Colour?

Due to the electronic transition of n (lone pair) to sigma* (antibonding sigma orbital) which fall under Visible light hence iodine shows violet color. For that mentioned transition iodine absorb red color light from visible region and emit violet color hence appear as violet.
