WebIts melting point is -248.4°C and its boiling point is -246°C. Neon is widely used in electrical signs and fluorescent lamps. It is present in less quantity in the earth’s … WebNoble gases have very low boiling and melting points, which makes them useful as cryogenic refrigerants. In particular, liquid helium, which boils at 4.2 K (−268.95 °C; −452.11 °F), is used for superconducting magnets, such as those needed in nuclear magnetic resonance imaging and nuclear magnetic resonance. picton medical centre bd8 8ra
How does the boiling point of the noble gases change down the …
WebThe noble gases are in Group VIII (or Group 0); they are non-metals and have very low melting and boiling points. They are all monoatomic, colourless gases. The Group 0 elements all have full outer shells. This electronic configuration is extremely stable so these elements are unreactive and are inert.

This happens because as we go down the periodic table, the atoms become larger (they have higher relative atomic masses), which results in stronger intermolecular forces of attraction. picton medical centre online
