Problem 8 : Explain the properties of the halogens (Group 17) in terms of their reactivity and physical states.
Solution :

Halogens (Group 17):

  • Reactivity: Halogens become less reactive down the group, with fluorine (F) being the most reactive and astatine (At) the least reactive.
  • Physical states: Fluorine and chlorine are gases at room temperature, bromine is a liquid, and iodine and astatine are solids.
