Question

If Th-234 emits a beta particle, what nucleus is formed?

Answer 1

Given:

The parent nucleus is,

`Th^(234)`

To find:

The product when Th-234 emits a beta particle

Step-by-step explanation:

When a particle emits a beta particle, the atomic number increases by 1, but the mass number remains the same.

So,

`Th_(90)^(234)-\beta=Pa_(91)^(234)`

Hence, the product is Pa-234 with atomic number 91.
