The alpha decay of what isotope of what element produces lead-206? the alpha decay of what isotope of what element produces lead-206? mercury-202 thallium-204 bismuth-208 polonium-210 radon-222

Answer : The element produces lead-206 is, polonium (Po)- 210

Explanation :

Alpha decay : In this process, 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 reaction is:

As we are given that,

From the given data we conclude that,

So, the element is polonium (Po) that has atomic number 84 and atomic mass 210.

The complete alpha decay reaction will be,

Hence, the element produces lead-206 is, polonium (Po)- 210

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.
