Periodic Table

Atomic Radius

100

The largest atomic radius in Group 1

Fr

200

Which has a smaller atomic radius: Ca⁺ or Sr²⁺?

Sr²⁺

300

Which has a larger atomic radius: Na or Na⁺?

Na⁺

400

Does Fr or Lr have the greater atomic radius?

Fr

500

Why does Br^- have a greater atomic radius than Sr²⁺?

Sr²⁺ has lost 2 electrons, and remains with more protons which pull the electrons in closer, while Br^- gains an electron and has fewer protons than electrons, meaning the protons cannot pull the electrons as close.
