Sublimation describes a solid turning directly into a gas. Melting occurs when a solid turns into a liquid. Water can, under the right circumstances, sublimate, though it usually melts at temperatures above 0 degrees Celsius or 32 degrees Fahrenheit.
Explanation: Carbon dioxide (CO2), however, is very different. The conditions that determine whether CO2 melts or sublimates are both temperature and atmospheric pressure.
Sublimation is the process in which a solid molecule converted directly into gas while melting is a process in which a solid molecule converted first into liquid . and No all the materials cannot be sublime .
1S^2 2S^2 2P^6 3S^2 3P^6 4S^2 3d^10 4P^6 5S^2 4d^10 5P^5 when Krypton is the noble gas in the row above iodine in the periodic table, we can change 1S^2 2S^2 2P^6 3S^2 3P^6 4S^2 3d^10 4P^6 by the symbol [Kr] of Krypton.
So we can write the electron configuration of Iodine: [Kr] 5S^2 4d^10 5P^5
