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

∙ 13y agoThe boiling points of the members of last four groups of Periodic Table including Halogens increase from top to bottom with the rise of atomic size, it is due to the increase in molecular size which is responsible to increase the Vander waal's forces among the molecules.

∙ 13y agoGenerally speaking, as the molecular weight increases, the boiling point also increases.
There are all kinds of exceptions to this, but assuming you're talking about similar compounds, it's a good rule of thumb.

What is the trend in density as you go down the group of halogens?
The density increase down.
How can you account for the fact that all halogens easily become gases?
Molecules of a halogen e.g. Cl2 are attracted together the weak Van Der Waals forces. these forces can be easily broken with a very small amount of heat, meaning that these halogens have very low boiling points, this allows the halogen to exist as a gas naturally due to its low boiling point.
When was Boiling Points created?
Boiling Points was created on 2004-01-05.
Molecular compounds have relatively high boiling points?
false they tend to have low boiling points
Do the halogens have a higher boiling point going down the group and why is that?
yes they can get angry really fast
What is the trend in melting points as you go down the group of halogens?
The melting point is greater.
What do you notice about the boiling points as you move from left to right across the periodic table?
The trend of boiling points across a period in the periodic table should decrease from metals to nonmetals. The trend becomes more complicated between metals, the boiling point of metals tends to increase across a period.

The density increase down.

What are two prperties of the halogens?
They have low melting and boiling points which increases down the group. They form diatomic molecules They form simple ions with -1 charge They react with hydrogen to form acidic compound
When did Boiling Points end?
Boiling Points ended on 2005-01-01.
When was Boiling Points created?
Boiling Points was created on 2004-01-05.
Explain how the trends in melting point and boiling point differ from the other periodic trends?
Instead of generally increasing or decreasing trend, melting and boiling points reach two different peaks as d and p orbitals fill. -Darryn
Comment on the trend in the boiling points of the Noble gas elements and why do boiling points vary in this manner.?
According to the trend, the boiling point of the noble gases decreases down the group, as you know the number of shells increases down the group but the number of valency electrons remains the same. the further away the nucleus is to the outer electron, less the attraction. Therefore, resulting in less energy needed to change the state of the element which brings us to the conclusion of decrease in the boiling points of noble gases down the group. I hope it helps Cheers mate !
