Nuclear Fission

Question 1

What is nuclear fission?

Answer 1

(Random Process) Nuclear fission occurs when an atomic nucleus splits into two or more smaller nuclei when bombarded with particles such as a neutron.

Question 2

Why is neutron most compatible for fission?

Answer 2

This is because a neutron has a neutral charge, so it will experience none/less repulsion from atomic nuclei.

Question 3

Fissile Meaning?

Answer 3

Fissile refers to nuclei that have the ability to undergo fission.

Question 4

Define the mass-energy balance.

Answer 4

E=mc^2 states that the mass of a particle is directly proportional to its energy. Therefore, if a reaction absorbs or emits energy, then a change in mass must accompany the reaction.

Question 5

Mass-energy balance equation:

Answer 5

E = mc^2
E = Energy in joules (J)
m = Mass in Kg (Kg)
c = Speed of light (3 x 10^8) m s^-1

Question 6

Define nuclear binding energy:

Answer 6

Nuclear binding energy refers to-energy that is required to separate an atomic nucleus into its constituent nucleons.

Question 7

Define mass defect:

Answer 7

Mass defect refers to the difference in mass in nuclei.
