multiple - choice question\nwhy does cs have a larger radius than rb?\nbecause rb has 1 more electron shell than cs\nbecause cs has 1 more electron shell than rb\nbecause cs has more protons than rb\nbecause cs has 1 less electron shell than rb\nrewatch
Answer
Brief Explanations:
Atomic radius generally increases with the addition of electron - shells. Cs (cesium) has a larger atomic radius than Rb (rubidium) because Cs is below Rb in the periodic table and has one more electron - shell. Protons do not account for the size difference in this case as the increase in the number of electron - shells is the dominant factor for atomic size trends down a group.
Answer:
Because Cs has 1 more electron shell than Rb
