For a start not all the other halogens are gases only chlorine and fluorine, bromine is a liquid and astatine is also a solid. The increase in boiling/melting point as you go down the group is due to the fact the intermolecular forces get stronger. Halogens are non polar, so the only forces between the molecules are van der waals' forces, these forces come from random movement of electrons, When electrons sway in one direction they make that side slightly more negative than the other forming a temporary dipole, this in turn induces a dipole on the molecule next to it, the slightly negative side is then attracted to the slightly positive side. The more electrons the more random movement of electrons and hence stronger van der waals' forces. Iodine has 106 electrons (its a diatomic molecule), this is alot more than chlorine and fluorine hence why iodine is a solid and the others aren't (excluding astatine).

Are all halogens gases at room temperature?
no bromine is liquid and iodine is solid at room temp
The solid halogen?
Halides are minerals that contain a halogen ion plus one or more other elements. Halogens are elements from Group 7A of the periodic table. This group includes the elements fluorine and chlorine.
How do halogen molecules exist?
Halogens are considered to be diatomic molecules. They exist in gas (F2, Cl2), liquid (Br2) and solid phase (Iodine I2).
Is iodine solid a conductor?
No solid iodine does not conduct electricity.
What are the 2 halogens with the highest melting points?
Melting points increase with atomic weight for elemental halogens (the second-most right column in a periodic table). The heavier the atom, the harder to turn it into a liquid. The lightest halogens, such as Florine (F) and Chlorine (Cl) are gasses at room temperature, having "melted" and "boiled" at lower (colder) temperatures. The two heaviest halogens are Iodine (I) and Astatine (At). Astatine is very rare, but Iodine is common and is a solid at room temperature. The have the highest melting points of halogens. Remember, F down to At increase in melting points. F and Cl are gases, so they have low melting point. Br is a liquid, so it has a higher melting point. I and At are solids so it takes more heat to melt them.
How does iodine differ from other halogens?
Iodine is solid and less reactive.
Are all halogens gases at room temperature?
no bromine is liquid and iodine is solid at room temp
What trends the periodic table should be expected as the atomic number decreases in the halogens?
Halogens with lower atomic number are more reactive and less dense. Also iodine is solid, bromine liquid and the first halogens are gases.
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
Why does iodine emit a purple gas when heated?
Because iodine sublimates, as do the other solid halogens. That means they go from solid to gas without becoming a liquid first.
How does bromine differ from the other halogens and nonmetals?
It is a brown liquid under normal conditions,fluorine and chlorine are gases iodine is a solid. The other non metals are gases or solids. Chemically it is similar to the other halogens, forming compounds with Br- ion, forming a single covalent bond is compounds like methyl bromide. Bromine- a non metal liquid at room temperature.
Which of the halogens is a solid at room temperature?
Iodine and astatine are solids at room temperature.
How do halogens differ from noble gases?
halogens are much more reactive
How do the physical and chemical propertys of the halogens compare with those of the inert gases?
Halogens can be gaseous, liquid or solid; noble gases are only gases.Halogens are very chemical reactive elements; only some compounds of noble gases are known.
