As you go down any group in the Periodic Table of elements, you are moving in the direction of heavier elements. And heavier elements within a group are going to boil at higher temperatures than lighter elements, because heavier atoms have more inertia, and require more energy in order to give them the amount of random thermal motion needed to form the gas phase.

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 !
What happens to the size of the atoms as you move down the periodic table in group 7?
Down the group, size increases. Because number of shells increases.
What happens to the reactivity as you move down group 1 in the periodic table?
Reactivity in group 1 of elements increases as we go down the group (to francium) because in the alkali metals as we go down the group number of atomic shells increases so the elements with most shells will easily release their electrons in the outer most shell.
Why hydration energy decreases down the group in periodic table?
In fact it increases down the group because ionization energy decreases down the group
What property increases going down a group in periodic table?
Atomic size, number of shells (or energy levels) and electropositivity increases down a group on the periodic table.
How do boiling points of the noble gases change as you go down the group?
Down the group generally boiling point increases. And this is true in the case of noble gases or group 18 also.
What is group trend of boiling point in IA group?
The boiling point decrease from lithium to caesium.
Why boiling point of noble gases increase down in the group?
The melting and boiling points increase down the group because of thevan der Waals forces. The size of the molecules increases down the group. This increase in size means an increase in the strength of the van der Waals forces.
How do the boiling points of the noble gases change as you go down?
The boiling points of noble gases increases down a group.
Why boiling point increases from top to bottom in group 8?
This is due to increased london dispersion forces- simply put the more electrons in the atoms the bigger the force - as you go down the group the atomic number increaes and therfore the number of electrons increases..
Do the halogens have a higher boiling point going down the group and why is that?
yes they can get angry really fast

Which is true moving down a column or group in the periodic table?
Atomic radius increases down a group. Metallic character also increases down the group.
What are the Properties of an alkali liquid?
The alkali metals have the following properties in common:they have low melting and boiling points compared to most other metals.they are very soft and can be cut easily with a knife.they have low densities (lithium, sodium and potassium will float on water)
Why melting point decrease down the group for Alkali metals but increase for Halogens?
Because the atomic radius increases down the group 1 and decreases down the group of halogen
Why basic character of alkali metals increases down the group?
Basic character depends upon electron loosing tendency of an element which increases down the group,SO basic character of alkali metals increases down the group
Does boiling point of water slow down with salt?
no. it does not any impurity in water and other all substances rises its boiling point and slows down its melting point . So salt will raise the boiling point of water rather than lowering it
