Expert Answer

Step 1

The absorption of a neutron results in the increase of the mass number by 1, while the atomic number remains same. This can be represented as :

Chemistry homework question answer, step 1, image 1

Step 2

Given,

²³⁵U absorbs a neutron, it forms an unstable nuclide that ultimately fissions into smaller nuclides.

 

Mass number of U = 235

Atomic number of U = 92

 

The absorption of a neutron by ²³⁵U will resul...
