Question

Polonium is the only element having Simple cubic crystal structure...... How it is possible..... because stacking sequence of A layer of atoms above A layer is not possible

Answer 1

thats why polonium is not stable continue sly undergo disintegration!!!!!

Answer 2

CAn you please elaborate your answer @chmvijay

Answer 3

According to the American Institute of Physics, the" mass-velocity term (describing the relativistic increase in mass of electrons traveling with velocities comparable to the velocity of light) [is] the cause of the simple-cubic structure of polonium." http://www.aip.org/pnu/2007/split/828-2.html
