Simple cubic structure there is only one lattice point at each corner of the cube-shaped unit cell. Here, particles are present at the corners of the cube and not on the body center or face center.
Alpha polonium is a high radioactive heavy metal.
How to calculate density in simple cubic cell?
We will use the equation,
ρ=Z×Ma/a³×Na
where,
Z = number of atoms in a unit cell (Z = 1 for a simple cubic unit cell)
a = edge length= 336 pm
Na=6.022×1023particles/mol
Ma = 209
ρ=Z×Ma/a³×Na
= 1× 209 / (336) ³× 6.023
= 3.31 ^-5
