Data Sources and units

[steto123]

Hello,

congratulations for your nice work.
I have a simple question (or 2): What are the sources for your elemental data? And i am missing the units for some of this data.
For example: AtomicRadius of boron is given aus 1.2. I think this is Angstroem? The value found on other sites is significantly smaller than this value. A second example is the first ionisation energie of boron ( i use boron as programming example). The value given is 8.298. What is the unit? The value found in literature is 800.6 kj/mol, so i think this value is eV?

Sincerly
