(a)
Interpretation:
The radionuclide formed by the decay of
Concept Interpretation:
A radioactive metal with a silvery-gray color and the molecular symbol
(a)
Answer to Problem 41A
Explanation of Solution
When a radioactive nucleus decays, the atomic nucleus emits an alpha particle (similar to that of a helium nucleus), after which the nucleus is transmuted into a different
This is how an alpha decay's
Since an alpha particle (helium nucleus) is emitted in alpha decay, the mass number
When Plutonium
The end result is uranium
(b)
Interpretation:
Concept Interpretation:
(b)
Answer to Problem 41A
Explanation of Solution
When a radioactive nucleus decays, the atomic nucleus emits an alpha particle (similar to that of a helium nucleus), which is followed by the nucleus changing into another atomic nucleus.
This is how an alpha decay's nuclear equation looks:
Since an alpha particle (helium nucleus) is emitted in alpha decay, the mass number
When Bismuth
The substance is thallium
