The half lives of elements beyond uranium are too short for these elements to occur in natural deposits. But elements below uranium that have equally short half lives do occur in natural
Deposits. This is because they are
A) bound with longer-living elements.
B) the small leftover of huge abundances when the Earth formed.
C) subdued and preserved by pressures beneath the Earth.
D) the products of uranium decay.

Question

Quizplus · Accepted Answer

Elements below uranium that have short half lives can still be found in natural deposits because they are continuously produced as the decay products of longer-lived elements like uranium. This ongoing process replenishes these elements, allowing them to be present despite their short half-lives.
