Question

What type of element did fermi expect to find when uranium absorbed a neutron and then ejected a beta particle? what did they find ( they were identified by someone else much later.) what reason did fermi and his group give for not being able to identify the products? answer?

Answer 1

Answer: a)neptunium b) the element is unstable

Step-by-step explanation:

a) 238 0 239 -1

U + n = Np e

92 1 93 0

b) it is an isotope of neptunium with half-lives less than 4.5 days, with most less than 50 minutes. It is therefore not stable that's why they where unable to identify it
