2. Why are the more reactive elements higher up in group 7?

  • The electrons are closer to the nucleus, stronger forces, easier to gain an electron.
  • The electrons are further from the nucleus, meaning there is a weaker attraction so it is easy to lose an electron.

3. Why are the more reactive elements further down the group in group 1?

  • The electrons are further from the nucleus, meaning there is a weaker attraction so it is easy to lose an electron.
  • The electrons are closer to the nucleus, meaning there is a stronger attraction meaning it is easier to lose an electron
