Description

Properties of Noble Gases

Noble gases are found in Group VIII of the periodic table. They are characterized by their lack of reactivity and exist as single atoms. Each noble gas has a complete outer electron shell, which contributes to their stability.

  1. a

    Explain why noble gases are unreactive and how their electronic structure relates to this property.

    Aim for approximately 3 distinct marking points.
