Iodine is bigger hence there is stronger van der waals forces and thus it is solid.
bromine,chlorine and iodine do not have the same physical properties like chlorine is a greenish yellow gas,bromine is brown and iodine is purple liquid so generally they do not have the same physical properties.
Iodine
The original state of matter of chlorine is gas. Chlorine is a halogen, of which group there are only one element is solid at room temperature (Bromine) and one a liquid (Iodine).
iodine
Fluorine, Chlorine, Bromine, Iodine, and Astatine.
bromine,chlorine and iodine do not have the same physical properties like chlorine is a greenish yellow gas,bromine is brown and iodine is purple liquid so generally they do not have the same physical properties.
Chlorine is not a compound, it is an element. That means that if you have a pure sample of chlorine then it will not contain iodine, or anything other than chlorine. It would be somewhat unlikely to find iodine as an impurity in chlorine, because iodine is solid at room temperature while chlorine is a gas.
At room temperature, fluorine and chlorine are gases, bromine is a liquid, and iodine and astatine are solids.
Only fluorine and chlorine are gases at room temperature. Bromins is a liquid. Iodine and astatine are solids.
iodine has lower electronegativity than chlorine
Iodine
None of them are Fluorine, Chlorine and Bromine are all gases at room temperature. Iodine and Astatine are both solid at room temperature.
At room temperature and pressure, fluorine and chlorine are gases, bromine is liquid and iodine is a solid
The original state of matter of chlorine is gas. Chlorine is a halogen, of which group there are only one element is solid at room temperature (Bromine) and one a liquid (Iodine).
Hydrogen, nitrogen, oxygen, fluorine and chlorine are gases at room temperature; iodine is a solid, bromine is a liquid.
Both iodine and chlorine cause various degrees of corrosion. However, the corrosion effect of chlorine is dramatically more than iodine.
The same? No. Similar? yes, Flourine, Bromine, Iodine. See "HALOGENS"
