Exam points
- identify nucleons as particles affected by the strong nuclear force and distinguish them from leptons in force questions
- identify the proton as experiencing both the strong nuclear force and the Coulomb force because it is a nucleon with charge
- use particle type and electric charge to determine which fundamental interactions apply in a stated nuclear context

IB Physics SL E 3 5 Strong Nuclear Force Questions question 1
[Maximum number: 2]
The neutron number N and the proton number Z are not equal for the nuclide 81205Tl. Explain, with reference to the forces acting within the nucleus, the reason for this.
Reference to proton repulsion OR nucleon attraction strong force is short range OR electrostatic/electromagnetic force is long range more neutrons «than protons» needed «to hold nucleus together»
