Question

explain why noble gases have low boiling and melting points.

Answer 1

The noble gases have weak interatomic force, and consequently have very low melting and boiling points

Answer 2

can you provide a more detailed explanation?

Answer 3

they are stable elements, unreactive, all noble gases have 8 electrons in the outermost shell,there's no lone pair or radical to bond with other elements and form compounds and eventually turns into solid or liquid..

Noble gases has no poles, which means the entire atom is neutral, ions are unable to attract towards noble gases.

Answer 4

Atoms of the noble gas do not stick to anything

Answer 5

because they are stable/ very low/ un - reactive
this is cause their outter shell of electrons is full

EG- Sodium, Na, is 11 on the periodic table.
So its electron configuration is:
2, 8, 1
Its outer shell, which has one electron is not full because it must have 8 electrons to be full as it is the third shell.
Therefore for it to be stable it can either gain 7 electrons, which would be difficult, or it can loose one electron, which is easy.
So sodium finds another atom to share its one electron with and then becomes an ION of Sodium, making it an anion, which is just what u call positviely charged ions.

That is what sodium needs to go through to become stable.

This isnt the problem for noble gases because their outter shells are full with either 2, 8, 18 electrons

They have a low boiling point because it is also ver close to its melting point, because they are so unreactive

helium i think boils at about 4degrees, but it melts at only about -5 degrees, thats only 9 degrees difference.

So yea...
