What is nuclide notation?Show answer
A nuclide is a specific nuclear species, written:
What are isotopes?Show answer
Isotopes of an element have the same proton number but different nucleon numbers , that is, the same number of protons but different numbers of neutrons. They are chemically identical but differ in mass and may differ in nuclear stability. Carbon-12 and carbon-14 are isotopes of carbon.
What are balancing nuclear equations?Show answer
In any nuclear reaction or decay, two quantities are conserved:
What is not conserving charge?Show answer
Both the top (nucleon) and bottom (proton) numbers must balance on each side of a nuclear equation.
What is q1?Show answer
State the two key observations of the alpha-scattering experiment and what each shows. [2 marks]
What is q2?Show answer
Write the nuclide notation for an isotope of oxygen with protons and neutrons. [1 mark]
What is q3?Show answer
A polonium-210 nucleus () emits an alpha particle. Identify the daughter nucleus by its nucleon and proton numbers. [2 marks]
