another name for Group 0
Group 0 is also known as the noble gases.
how does the Outer shell of Group 8 elements look
The outer shell of Group 8 elements is full, with 8 electrons except for helium, which has 2.
what is the Reactivity of Group 0 elements
Group 0 elements are unreactive.
why do they have Low reactivity
The low reactivity of noble gases is due to their full outer shells, so they do not need to gain or lose electrons.
Common use of He
Helium is commonly used in helium balloons.
what Noble gases is used in lighting and why
Argon is used in lighting as it does not react with the metal filament.
how do noble gases look naturally
Noble gases exist as individual atoms in nature and do not form compounds with other elements.
Boiling point of noble gases
Noble gases have low boiling points and are gases at room temperature.
Density of noble gases
Noble gases have low densities.
what is the Noble gas used in street signs
Neon is used in street signs.
how the Boiling point of noble gases in Group 0 change as you go down the group
The boiling points of noble gases increase as you move down the group, indicating an increase in the strength of intermolecular forces.
why is He used for helium balloons (give 2 reasons)
Helium is suitable for use in helium balloons because it is unreactive and less dense than air.
