B. Fission of atoms of U235
C. Fusion of atoms of U235
D. The breaking of U235 bonds​

Answer 1

Answer:

Nuclear energy is derived by

Option (B): Fission of atoms of U235

Explanation:

Nuclear Fission :

Nuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nuclei. The fission process often produces gamma photons, and releases a very large amount of energy even by the energetic standards of radioactive decay.

Fission of U235:

When a neutron is absorbed by uranium-235 atom it becomes unstable due to large weight number(236) and fissions into two new atoms (fission fragments) which are Barium-141 and Kripton-92 and releas three new neutrons and some binding energy that is about 200 Mega Electron Volts (MeV).

The fission reaction is given by;

$</u></strong></p><p><strong><u>[tex]0 {n}^{1}  +</u></strong></p><p><strong><u>[tex]0 {n}^{1}  +92 {U}^{235}  →</u></strong></p><p><strong><u>[tex]0 {n}^{1}  +92 {U}^{235}  →56 {Ba}^{141}  +</u></strong></p><p><strong><u>[tex]0 {n}^{1}  +92 {U}^{235}  →56 {Ba}^{141}  +36 {Kr}^{92}  + 3 (0 {n}^{1} ) + 200 \: MeV$

These three new neutrons continue collision with other U-235 and the chain reaction is Started that can produce a huge amount of energy in very short time that is used in Nuclear Fission Bombs.
