Chlorine is a greenish yellow gas at room temperature and atmospheric pressure.
Chlorine solid at room temperature.
At room temperature hydrogen chloride is a colourless gas like all the hydrogen halides apart from hydrogen fluoride since hydrogen cannot form strong hydrogen bonds to the larger electronegative chlorine atom.
Their group number only describes the number of electrons they have in their outer shell.
Chlorine chlorine physical and chemical properties.
As iodine has a higher atomic number than chlorine it also has more electrons in its electron shells.
Density g cm 3 density is the mass of a substance that would fill 1 cm 3 at room temperature.
In contrast sodium chloride is a solid at room temperature as it is a giant ionic compound.
Sublimation the transition of a substance directly from the solid to the gas phase without passing through a liquid phase.
Relative atomic mass the mass of an atom relative to that of.
It has a choking smell and inhalation causes suffocation constriction of the chest tightness in the throat and after severe exposure edema filling with fluid.
However weak hydrogen bonding is present in solid crystalline hydrogen chloride at low temperatures similar to the hydrogen.
Iodine is further down group 7 than chlorine.
Therefore chlorine has a low boiling point and so is a gas at room temperature.
14 696 psia 101 325 kpa 149 76 f 100 98 c solubility in water.
The weight of chlorine which can be dissolved in a given amount of water at a given temperature when the total vapor pressure of chlorine and the water equals a designated value.
Why is iodine a solid at room temperature and chlorine a gas despite being in the same group.
It becomes a liquid at 34 c 29 f.
The temperature at which solid chlorine melts or liquid chlorine solidifies.
