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?

a)neptunium b) the element is unstable

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

your answer would be “dry”
