IB Physics SL E 1 2 Nuclear Notation Questions

Use SL nuclear notation to identify protons, neutrons and nucleon number, balance nuclear reactions and distinguish isotopes from nuclides.

Exam points

interpret nuclide notation to determine proton number, nucleon number, neutron number and the identity of an isotope
balance alpha, beta and other nuclear reactions by conserving nucleon number and charge, then write the missing nuclide correctly
distinguish isotopes and related nuclei from their proton and neutron counts and select the correct nuclear symbol in exam questions

[Maximum number: 1]

Tritium may be produced by bombarding a nucleus of the isotope lithium-7 with a high-energy neutron. The reaction equation for this interaction is

{ }_{3}^{7} \mathrm{Li}+{ }_{0}^{1} \mathrm{n} \rightarrow{ }_{1}^{3} \mathrm{H}+{ }_{Z}^{4} \mathrm{X}+{ }_{0}^{1} \mathrm{n} .

Identify the proton number Z of X.
