The boiling points of halogens generally increase as you move down the group from fluorine to iodine. This is due to the increase in the size and relative Atomic Mass of the atoms, which leads to stronger van der Waals forces between the molecules.
The 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.
Generally 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.
Atom gets larger, and The outer electron shells are farther from the nucleus.
The reactivity of the halogens decreases as atomic number increases.
Melting and boiling points of halogens increase down in the group.
They increase. Fluorine and chlorine are gases at room temperature, bromine is a liquid, and iodine is a solid.

How can you account for the fact that all halogens easily become gases?
Halogens easily become gases because of their low boiling points and weak intermolecular forces. As you move down the halogen group in the periodic table, the atomic size increases, which leads to weaker intermolecular forces, making it easier for the halogens to transition from a solid or liquid state to a gas at relatively low temperatures.
Do the halogens have a higher boiling point going down the group and why is that?
Yes, halogens have a higher boiling point going down the group. This is because the atomic size increases with atomic number, leading to stronger London dispersion forces between molecules as the size increases. Consequently, more energy is required to overcome these forces, resulting in higher boiling points.
What is the trend in density as you go down the group of halogens?
The density increase down.
When was Boiling Points created?
Boiling Points was created on 2004-01-05.
Do the Physical and chemical properties of halogens compare that of noble gases?
No, the physical and chemical properties of halogens are different from noble gases. Halogens like fluorine, chlorine, bromine, and iodine are highly reactive and can form compounds with other elements, while noble gases like helium, neon, and argon are inert and do not readily form compounds. Halogens typically have higher melting and boiling points compared to noble gases.
What is the trend in melting point and boiling points of the elemets in group 1 and 7?
In Group 1 (alkali metals), the melting and boiling points decrease as you move down the group due to the increase in atomic size and metallic bonding. In Group 7 (halogens), the melting and boiling points increase as you move down the group due to the increase in atomic size and London dispersion forces.
What is the trend in melting points as you go down the group of halogens?
The trend in melting points as you go down the group of halogens is that they generally increase. This is due to the increasing number of electrons and atomic size which results in stronger van der Waals forces between the atoms, leading to higher melting points.
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.

Comment on the trend in the boiling points of the Noble gas elements and why do boiling points vary in this manner.?
The trend in boiling points of Noble gas elements increases down the group, from helium to radon. This is because as you move down the group, the atomic size and London dispersion forces also increase, leading to stronger interatomic forces and higher boiling points. Additionally, the increasing number of electrons in the heavier Noble gases results in more polarizable electron clouds, further contributing to the trend.
When was Boiling Points created?
Boiling Points was created on 2004-01-05.
When did Boiling Points end?
Boiling Points ended on 2005-01-01.
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
Is a boiling point a chemical property of a sustance?
No, boiling points and freezing points are physical properties.
