How many neutrons will be produced as a by-product of each reaction? Write the nuclear equation for this reaction.

• 13. When bombarded with neutrons, lithium-6 produces an alpha particle and an isotope of hydrogen. Write the nuclear equation for this reaction. What isotope of hydrogen is produced? • 14. Neutron bombardment of plutonium-239 yields americium-240 and another particle. Write the nuclear equation and identify the other particle produced. • • 15. One method of producing plutonium-240 is by bombarding uranium-238 with deuterium (hydrogen-2), which produces neptunium-238 and 2 neutrons. The unstable neptunium then decays to produce plutonium-240. Write the nuclear equations for this two-step reaction. What other particle is produced in the second reaction?
