1) Why Francium is the biggest element with the lowest IE and EN?
Francium is the biggest element with the lowest IE and EN because it has more energy levels and it has thesmallest amount of protons in its nucleus.
2) Why Helium is the smallest element with the highest IE?
Helium is the smallest element because its at the very top so it has fewer amount of energy shells. it has thehighest IE because it holds its electrons very close and its hard to remove them.
