Question

When the u 235 nucleus is split into two equal daughter nuclei, the amount of energy released per nucleon would be?

Answer 1

Explanation:

To split an atom a neutron, travelling at just the right speed, is shot at the nucleus. Under the right conditions the nucleus splits into two pieces and energy is released. This process is called nuclear fission. ... This chain reaction very rapidly multiplies the amount of atoms split and the amount of energy released.

That is, 16.5 billion kJ of energy are given off every time 1 mol of uranium-235 undergoes this nuclear reaction. This is an extraordinary amount of energy.

Answer 2

Uranium-235 atom consumes a neutron and splits into two new atoms, discharging three new neutrons and some binding energy.

• The split procedure is illustrated by the following equation:

$92 {u}^{235} + 0 {n}^{1} →56 {ba}^{144} + 36 {kr}^{89} + 30 {n}^{1} </p><p></p><p></p><p>$

• Masses of reactants = 234.39 + 1.01 = 235.4amu
• Masses of products = 143.28 + 88.89 + 3(1.01) = 235.2amu

The energy released = mass difference =235.4−235.2=0.2amu

=0.2×931∼200MeV

Hence, 200Mev energy is released per nucleic.
