Question

Which element of group $17$ undergoes sublimation?

Answer 1

Element of group$17$ that undergoes sublimation:

• Chlorine and fluorine are known to be gases at normal temperature, while bromine and iodine are solids.
• Sublimation is the direct transfer of a material from solid to gas without going through the liquid stage.
• The elements of Group $17$ are known as halogens, and they are volatile non - metals that include fluorine, chlorine, bromine, and iodine.
• Only Iodine is a halogen that sublimates, or converts directly into a gaseous form without melting.
• At normal temperature, iodine is solid.
• Solid iodine is warmed under vacuum in a sublimation equipment in the laboratory.
