CHEMISTRY, M1 EQ-Bank 9

Explain why Neon, similar to other noble gases, does not easily form chemical bonds with other elements.

In your explanation, include Neon's electron configuration and how this relates to its position on the periodic table and its chemical characteristics.   (3 marks)

Show Answers Only
  • Neon is located in Group 18 of the periodic table and has an atomic number of 10.
  • Its electron configuration is 1s² 2s² 2p⁶. This configuration shows that Neon has a completely filled outer shell, a characteristic of noble gases, which contributes to its chemical inertness.
  • As a member of Group 18, Neon shares this fully filled valence shell characteristic with other noble gases, resulting in high stability and very low reactivity.

Physical properties (choose two):

  • Hard and tough metals, high densities, can be hammered into shape, good heat conductor, high melting/boiling points.

Chemical properties(choose two):

  • Less reactive than Group 1 metals, often have variable oxidation states, can form alloys, form coloured ions.
