E.3.5—Strong nuclear force 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»
