Answer:
Helium
Explanation: The ionization energy decreases from the top to bottom in groups. And increases from left to the right across a period. Therefor Helium has tge largest first ionization energy, while francium has one of the lowest.
Answer: Fluorine has a stronger "pull" on its electrons
Ionization Energy is a measure of how much energy it takes to "pull" an electron off of an element
