Question

The atomic symbol mc026-1.jpg represents lead-206 (Pb-206), an isotope that has 82 protons and 124 neutrons. Which atomic symbol could represent an isotope that undergoes radioactive decay to produce Pb-206?

Answer 1

Answer:

A) 238/92 U

Explanation:

Answer 2

Answer : The atomic symbol represent an isotope that undergoes radioactive decay to produce Pb-206 can be, Polonium (Po).

Explanation :

Alpha decay : In this process, the alpha particles is emitted when a heavier nuclei decays into lighter nuclei. The alpha particle released has a charge of +2 units.

The general representation of alpha decay,

$_A^Z\textrm{X}\rightarrow _{A-2}^{Z-4}Y+_2^4\alpha$

The balanced nuclear reaction for alpha decay of polonium-210,

$_{84}^{210}\textrm{Po}\rightarrow _{82}^{206}Pb+_2^4\alpha$

Hence, the atomic symbol represent an isotope that undergoes radioactive decay to produce Pb-206 can be, Polonium (Po).
