Answer:
The element with the larger ionization energy is lithium.
Step-by-step explanation:
Lithium has a larger ionization energy because it has a smaller atomic radius and a higher nuclear charge than francium. This means that the attraction between the nucleus and the outermost electrons in a lithium atom is stronger than in a francium atom, making it more difficult to remove an electron from a lithium atom. In other words, more energy is required to ionize a lithium atom compared to a francium atom.
