Chemical compound
Lead polonide is the polonide of lead , with the chemical formula of Pb Po . It occurs naturally, as lead is produced in the alpha decay of polonium.[ 3]
Preparation
Lead polonide can be formed by reacting polonium vapour and lead under a vacuum.[ 4]
Properties
Lead polonide has a sodium chloride structure, which is the same as lead telluride . It has a cubic crystal structure , with the space group Fm3 m (No. 225), with lattice constant a = 6.59 Å.[ 5]
