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]
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)
