Van der waals forces are present in all three chlorine, bromine and iodine, however the strength of the van der waals forces depend on the number of electrons. The more electrons present, the stronger the van der waals forces. Iodine has the most electrons as it is furthest down the group followed by bromine, followed by chlorine, therefore the van der waals forces are strongest in iodine and are strong enough to keep it a solid. However in bromine the van der waals forces are weaker as bromine has fewer electrons, so at room temperature there is sufficient energy to break some of these weaker van der waals forces, hence making bromine a liquid. Finally there are far fewer electrons in chlorine so the van der waals forces are very week so there is sufficient energy at room temperature to break these completely and render chlorine a gas.
The physical state of elements at room temperature is determined by their intermolecular forces. Chlorine exists as a gas due to weak van der Waals forces, Bromine is a liquid because its van der Waals forces are stronger than chlorine's, and Iodine is a solid because it has the strongest van der Waals forces of the three.
it basically has to do with the mass and dispersion forces. Iodine has the most mass and the most electrons, so it has the strongest dispersion forces and so is able to exist as a solid. And so on and so forth for bromine and chlorine
it is to do with the intermolecular forces that each element has... iodine has the strongest and is therefore a solid at room temperature... and chlorine has very weak intermolecular forces so it is a gas at room temperature.
Bromine is a chemical element, Br, atomic number 35, atomic weight 79.909, which normally exists as Br2, a dark-red, low-boiling but high-density liquid of intensely irritating http://www.answers.com/topic/odor. This is the only nonmetallic element that is liquid at normal temperature and pressure. Bromine is very reactive chemically; one of the http://www.answers.com/topic/halogen group of elements, it has properties intermediate between those of http://www.answers.com/topic/chlorine and http://www.answers.com/topic/iodine. Therefore, it is a liquid.

Are halogens all gases?
No, not all halogens are gases. Fluorine and chlorine are gases at room temperature, while bromine is a liquid and iodine is a solid.
What element are hydrogen H2 nitrogen N2 oxygen O2 fluorine F2 chlorine Cl2 iodine I2 bromine Br2?
Hydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), chlorine (Cl2), iodine (I2) and bromine (Br2) are diatomic molecules where two atoms of the same element are bonded together.
Element in the halide family that is liquid?
Bromine is a halogen element that is in liquid form at room temperature.
Bromine monochloride formula?
The formula for bromine monochloride is BrCl. It is a reddish-brown liquid at room temperature and is a chemical compound of bromine and chlorine.
What halogen and is a red liquid at room temperature?
Sounds like bromine. (It actually is.) Bromine is also volatile. A link is provided below.Yes that is correct but say if this quest was in an exam, you wouldn't write that.The answer is Bromine because the question clearly states, at room temperature this halogen is a liquid,and on any periodic table, bromine is a different colour to the other elements showing that it is a liquid or it melts close to room temperature. Bromine, Mercury, Gallium, Ceasium and Francium are all the same colour as each other. Also, yes. Bromine is volatile.Hope this helps! :)
Halogen that exist in the liquid state at room temperature?
Bromine is the only halogen that exists as a liquid at room temperature. All other halogens (fluorine, chlorine, iodine, astatine) are gases or solids at room temperature.
What is the state of matter at room temperature of halogens?
Halogens like fluorine, chlorine, bromine, and iodine exist in different states of matter at room temperature: fluorine and chlorine are gases, bromine is a liquid, and iodine is a solid.
Are all halogens gases at room temperature?
No, not all halogens are gases at room temperature. Fluorine and chlorine are gases at room temperature, bromine is a liquid, and iodine is a solid.
What hallogen is a liquid at room temperature?
Bromine is liquid at room temperature.Its symbol is Br.It has 7 valence electrons.
Which halogens are gases at room temp?
At room temperature, fluorine and chlorine are gases, bromine is a liquid, and iodine and astatine are solids.
Which halogens are gases?
Fluorine (F2), chlorine (Cl2), bromine (Br2), and iodine (I2) are halogens that exist as gases at room temperature and pressure. At standard conditions, fluorine and chlorine are diatomic gases, while bromine is a diatomic liquid and iodine is a solid.
Are halogens all gases?
No, not all halogens are gases. Fluorine and chlorine are gases at room temperature, while bromine is a liquid and iodine is a solid.
What state of matter do halogens exist in room temperature?
At room temperature and pressure, fluorine and chlorine are gases, bromine is liquid and iodine is a solid
What haiogen is a liquid at room temperature?
None of them are Fluorine, Chlorine and Bromine are all gases at room temperature. Iodine and Astatine are both solid at room temperature.
What halogen would be a liquid at 100 degrees?
Bromine is a halogen that is a liquid at room temperature (around 20°C) and remains a liquid up to around 58.8°C. At 100 degrees Celsius, bromine would also be in its liquid state.
What is the color of the gases Chlorine bromine iodine?
Chlorine is yellow-green, bromine is red-brown, and iodine is purple.
Does Bromine iodine and chlorine have similar physical properties?
Bromine, iodine, and chlorine are all halogens and have similar physical properties such as being non-metallic, diatomic molecules at room temperature, with relatively low melting and boiling points. However, their specific physical properties such as color, density, and solubility can vary due to differences in their atomic structure and intermolecular forces.
