Crystallography, diffraction, identifying the pure element

[adamaero]

Homework Statement

The only things you know about the sample are: (i) it has some kind of cubic lattice, and (ii) it is a pure element. Identify the element in the crystalline sample.
SC: R = 0.5a
FCC: R = 0.25a√2
BCC: R = 0.25a√3

Distances from Bragg peaks:
d1 = 0.2037 nm
d2 = 0.1746 nm
d3 = 0.1244 nm

Homework Equations

n λ = 2d_hklsin θ

d = a/√(h²+k²+l²)

The Attempt at a Solution

Assuming the above is correct, I'm stuck.
I think I need a table or something of each element. Extra
