Atomic Physicist vs Chemist

Question

Does atomic physicist deal with atomic radius of an atom? Imagine that we're calculating the atomic radius of iridium with given density and atomic weight. Who has better knowledge atomic physicist or chemist? According to me, atomic physicist is best choice to ask this question. However, I doubt it. Might I take your thinkings? Assume that you're asked to calculate the atomic radius of iridium, whom would you ask it? atomic physicist or chemist?

Answer 1

Even though I supplied an answer to this question when you first asked it, I'd personally ask the physicist.  Nothing against chemists, but I think a well-trained physicist would be better equipped to answer this. Just my personal opinion.
