→ 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.

Group \(\text{A:}\) Earth metals (aka “alkaline metals”)

→ Physical properties: shiny, silver coloured metals, low density, malleable.

→ Chemical properties: low melting/boiling points, ductile.
  

Group \(\text{B:}\) Halogens (aka the “fluorines”)

→ Physical properties: Group 7 elements are dull and brittle in solid form

→ Chemical properties: low melting/boiling points, poor conductors of heat and electricity.

Group \(\text{A:}\) Alkali metals

→ Physical properties: Group 1 metals are soft and shiny.

→ Chemical properties: They are highly reactive and have low melting/boiling points.
 

Group \(\text{B:}\) Noble gases

→ Physical properties: Group 8 elements are colourless gases with no odour or taste.

→ Chemical properties: They are virtually unreactive and all have cryogenic boiling points.
