OK, sure. But TFA doesn't mention any coating. I found a resource that corroborates what I said about behavior on water.[0] But it doesn't get into why that is

OK, sure. But TFA doesn't mention any coating.
I found a resource that corroborates what I said about behavior on water.[0] But it doesn't get into why that is.
And about density and electronegativity:
g/cm^3 χ (Pauling) 1st ionization energy (kJ/mol)
Li 0.535 0.98 520
Na 0.968 0.93 496
K 0.856 0.84 419
The difference in density is larger than that for electronegativity and 1st ionization energy. But yes, all three arguably play a role. Still, for Li vs Na, density seems like the major factor.
