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

A) 238/92 U

Step-by-step 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).
