Explain why the halogens decrease in reactivity as you descend the periodic table:

  • Group 7 elements crave an electron  so that they can become stable and have 8 outer electrons.
  • As you descend the PT, the halogens gain more shells distancing from the attraction of the nucleus containg protons.
