Group 0 (Noble Gases)
I can describe the properties of the noble gases, their uses, and explain why they are unreactive.
Lesson details
Key learning points
- Noble gases are in Group 0 of the periodic table and are unreactive.
- Noble gases are all gases at room temperature.
- They have complete outer electron shells, making them stable.
- Moving down Group 0 elements, atomic mass, density and boiling points increase.
Keywords
Inert - An inert substance is one which is not chemically reactive.
Noble gas - A noble gas is an element in Group 0 of the periodic table.
Common misconception
Confusing the spelling of "noble" with "Nobel" and misunderstanding why noble gases are named so.
Clarify that "noble" refers to their stability and lack of reactivity due to a full outer electron shell, meaning they don't need to bond with other elements.
Emphasise the various uses of these elements due to their inertness, such as in light bulbs.
