The grid shows a number of nuclides arranged according to the number of protons and the number of neutrons in each. A nucleus of the nuclide ⁷₃Li decays by emitting a β-particle. What is the resulting nuclide? [Figure 37.1]

This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.

ANuclide at (number of protons: 4, number of neutrons: 4)

BNuclide at (number of protons: 4, number of neutrons: 5)

CNuclide at (number of protons: 3, number of neutrons: 4)

DNuclide at (number of protons: 3, number of neutrons: 5)

✓ Correct answer

A: Nuclide at (number of protons: 4, number of neutrons: 4)
