Given an isotope with a neutron/proton ratio of 1.5, how does beta decay help it reach the band of stability?

• A. By absorbing electrons to stabilize the nucleus.
• B. By converting some neutrons into protons, reducing the neutron/proton ratio to approximately 1.
• C. By converting protons into neutrons, increasing the neutron/proton ratio.
• D. By emitting gamma rays to balance the neutron/proton ratio.

Answer: (B)
