The group 0 elements, the noble gases, are all unreactive non-metal gases. They show trends in their physical properties. Their uses depend on their inertness, low density and non-flammability.
Where in the periodic table are the noble gases?
On the far left
In the middle
On the far right
What is the most characteristic property of the noble gases?
They are inert
They have high densities
They are good conductors of electricity
Why are the noble gases unreactive?
They all have one electron in their outer shell
They all have a full outer shell of electrons
They all have a low density
What happens to the density of the noble gases as you go down group 0?
It stays roughly the same
Which of these could be the electronic configuration of a noble gas?
Which of the following is a use for argon?
As a shield gas when welding metals
To make the bubbles in fizzy drinks
To fill floating party balloons
Why is xenon sometimes used as the gas to fill filament light bulbs?
Because it has a high density
Because it does not react with metals
Because it is a good conductor of heat
What is the electron configuration of helium?
The boiling points of the first three noble gases are listed below:
Helium = -269 °C
Neon = -246 °C
Argon = -186 °C
Which of these could be about the boiling point (°C) of the fourth noble gas, krypton?
Which noble gas is used in weather balloons which carry measuring instruments high into the atmosphere?
