Vesnalui [34]

Explanation:

The halogen family and noble gases are similar in just one particular way, they are groups of non-metals. All members of these two groups are categorized as non-metals.

Here are some of the differences between them;

  • Halogens have 7 electrons in their outermost shell whereas noble gases have 8 electrons in theirs.
  • Halogens are highly reactive elements, noble gases are non-reactive.
  • Halogens are made up of electronegative elements where as noble gases are neither electropositive nor electronegative.
