Answer 1

Answer:

Explanation:

139Xe is the answer of this question

Answer 2

1) As a result of the process of electron capture ("K-capture") by 211At, the new isotope formed is:

(c) 211Po

• Electron capture is the process in radioactivity where a neutron of an electrically neutral atom absorbs electrons from inner orbitals basically the K shell and the L shell. The process results in the emission of neutrino. The process of electron capture by Astatine results in the formation of new isotope Polonium.

2) When 235U is bombarded with one neutron, fission occurs and the products are three neutrons, 94Kr, and

(a) 139Ba

• When uranium undergoes fission process using one neutron, it results in the formation of three neutrons along with Krypton and Barium. The reaction is: $235_U$ → $94_K_r+3n^1+139_B_a$

3) The explanation for how a beta particle is produced in the nucleus of a radionuclide and then ejected involves the conversion

a) proton to a neutron.

• In the beta decay, a beta particle is emitted from the nucleus as a result the real nucleotide is changed into an isobar of that nucleotide. If there is a beta decay of proton to neutron is followed by the emission of positron with a neutrino.
