<p><tt>google-ing Francium wikipedia...</tt></p>
<p>Bulk francium has never been viewed. Because of the general
appearance of the other elements in its periodic table column, it
is assumed that francium would appear as a highly reactive metal,
if enough could be collected together to be viewed as a bulk solid
or liquid. Obtaining such a sample is highly improbable, since the
extreme heat of decay caused by its short half-life would
immediately vaporize any viewable quantity of the element. <br>
</p>
<p>however it also says (i dont know on the basis of what) :
Density (near r.t.) 2.8–3.0 g/cm3 (extrapolated)[1]</p>

<div dir="ltr">I am searching for Francium lattice constant for
scf calculation and i could not find it. Then I assumed
Francium as a body centred cubic and calculated its lattice
constant as 5.58875 Angstrom. Is it right ?<br>
