Does iodine exist as a liquid?
As Mike notes, iodine can indeed be a liquid at atmospheric pressure between 113.7 oC and 184.3 oC.
What is the melting point for iodine?
236.7°F (113.7°C)
Iodine/Melting point
Is iodine a gas at 25 degrees?
Room temperature is usually taken as being 25°C. At this temperature, fluorine and chlorine are gases, bromine is a liquid, and iodine and astatine are solids.
Does iodine exist as liquid at room temperature?
Iodine, for example, at ordinary pressures can exist in the liquid state at temperatures in the interval from 113.6 to 184.4 °C (Petrucci, 2001).
What happens on heating iodine?
Iodine crystals slowly sublime at room temperature, and when heated they turn into deep-purple vapors.
What is the melting and freezing point of iodine?
What temp does iodine boil at?
363.7°F (184.3°C)
Iodine/Boiling point
Why is iodine a solid at room temp?
Despite intermolecular forces being a weak individual force of attraction, collectively they are very strong and the numerous forces between iodine molecules means that more heat energy is required to break these intermolecular forces and separate the molecules therefore iodine is a solid.
How much does a cubic meter of iodine weigh?
Iodine, liquid weighs 3.96 gram per cubic centimeter or 3 960 kilogram per cubic meter, i.e. density of iodine, liquid is equal to 3 960 kg/m³; at 120°C (248°F or 393.15K) at standard atmospheric pressure.
When does iodine go from liquid to gas?
Boiling Point (BP), Iodine changes its state from liquid to gas at 184.4°C (363.92°F or 457.55K) Iodine is a bluish-black orthorhombic crystalline system. Molecular formula: I 2. Elements: Iodine (I) Molecular weight: 253.809 g/mol. Molar volume: 64.093 cm³/mol.
Which is the correct atomic number for iodine?
The term “iodine” is sometimes used to refer to any of the many forms of iodine, which adds to the confusion. But iodine is an element, and technically iodine is I 2 which is two molecules of the element I which has an atomic number of 53 on the periodic table.
What is the temperature at which iodine melts?
At room temperature, it is a colourless gas, like all of the hydrogen halides except hydrogen fluoride, since hydrogen cannot form strong hydrogen bonds to the large and only mildly electronegative iodine atom. It melts at −51.0 °C and boils at −35.1 °C.
