They increase. Fluorine and chlorine are gases at room temperature, bromine is a liquid, and iodine is a solid.

The boiling point and the melting point of halogens is increasing from fluorine to iodine. Boiling points of halogens are: - Fluorine: -188,12 0C - Chlorine: -34,04 0C - Bromine: 137,8 0C - Iodine: 184,3 0C


Yes, as the larger the atomic weight the larger the boiling/melting points the halogens have. This is due to the larger atoms having larger van der walls forces due to the larger number of electrons.


They have low melting points and high reactivity.


Not all compounds have high melting points and high boiling points.


The boiling and melting points of pure substances vary based on the substance. Gasses for example have lower boiling and melting points than metals.


No. The melting and boiling points of liquids vary considerably.


Melting and boiling points are different for each compound or element.


Solids have higher melting and boiling points than liquids and liquids have higher melting and boiling points than gases.


A certain substance has certain melting and boiling points which is what helps identify a substance.


Impurities can increase or decrease the melting and boiling points of substances depending on what the impurity is.


They have high melting points and very high boiling points


Compounds with strong intermolecular forces have higher melting and boiling points.




melting: 115.21 ºC boiling: 444.6 ºC


chloride isn't a thing on its own and the melting and boiling points of chlorine and magnesium will have no effect on the boiling and melting point og magnesium chloride.



Many substances have different melting and boiling points, thus one can use their melting and boiling points to identify them.



The boiling and melting points are very different.


Boiling and melting points are very different.


The boiling point increases as the atomic number of the halogens increases. This can be explained with London dispersion forces becoming more evident due to a the larger amount of polarized electrons.


mixture has varialble boiling and melting points, compound has a fixed boiling and melting and elements also have fixed boiling and melting point


The boiling and melting point of Glucose To find the boiling point you boil it and to find the melting point you have to freeze it and melt it.


the relationship between the melting points and boiling points is simply that the higher the melting point, the higher the boiling point. the metal has to melt before it can boil, so if it didn't melt, it won't boil. there fore, the higher the melting point, the higher the boiling point ill be.
