Which of the following atoms has the smallest radius? At, Br, Ge, or Pb? Which of the following atoms has the smallest radius? At, Br, Ge, or Pb? The answer is Ge. Based on trends, wouldn't Br have a smaller atomic radius than Ge? Can you please explain why Ge has a smaller radius than Br? OR just solve the question and explain why Ge is the answer? Thank you in advance.
