Walker Leach · Answer 1

Answer: U-234

Explanation: no matter how much of beta decay, the mass number of the resulting element is unchanged

Agustin James · Answer 2

The answer to your question is U-234

Explanation:

Data

Thorium-234

beta emission twice

Definition

Beta emission is when a beta particle (electron) is emitted from an atomic nucleus.

First beta emission

²³⁴₉₀Th ⇒ ²³⁴₉₁Pa + e⁻

Second beta emission

²³⁴₉₁ Pa ⇒ ²³⁴₉₂U + e⁻

The atom will be Uranium-324
