Confirming atomic radius/volume data

[egsutherland]

Hello,

I am a PhD student and have been using the XenonPy elements_completed data for my research. I have discovered that the data for atomic_radius does not match that from mendeleev, which cites The Journal of Chemical Physics, 41(10):3199, 1964 for atomic radius. I am wondering if the atomic_radius data reported by XenonPy is from a different source, or if there is a mistake in the data? I am also wondering what is the source for the atomic_volume data reported by XenonPy?

Thank you,
Emily
