Question:
Radioactive decay will occur as follows:
\(_{86}^{220}Rn→_{84}^{216}Po+_2^4He\); Half life = 55s
\(_{84}^{216}Po→_{82}^{216}Pb+_2^4He\); Half life = 0.66s
\(_{82}^{812}Pb→_{82}{212}BL+λ^oe\); Half life = 10.6 h
If a certain mass of radon (Rn=220) is allowed to decay in a certain container; then after 5 minutes the element with the greater mass will be
