table salt is NaCl (sodium chloride) so its either sodium or chlorine
chlorine is a green gas so it cant be that
sodium is a light silvery solid so it cant be that
the question doesn't seem to make much sense
When it is iodine (I2) it is only physical sublimation of the black (metallic shiny) I2 crystals into purple heavy gas clouds or fumes
Iodine
You think to iodine.
No, boron is black or brown solid. A shiny silver liquid is mercury (Hg)
Iodine ------------------------------------------- The element you describe sounds like iodine, a good test to make sure that it is iodine is to see if the substance sublimes. This means a solid sample of iodine will turn straight from a solid into a gas with no liquid stage.
Iodine on heating gives off dense purple vapor.

Iodine is a purple-black non metal that changes to a deep purple gas when heated.
Iodine is naturally found in solid form.
Shiny pokemon are found in random throughout the game. There is no solid way to get one.

This is a physical change. The solid is Iodine, which sublimes on heating to form gaseous Iodine. When cooled, it sublimes again to form solid Iodine. Since this change is only the change of physical states, and since there's no change in the chemical structure of Iodine, this is a physical change.
