An alpha (a) particle is the nucleus of a 4He atom and consists of 2 neutrons and two protons bound together. Let's take apart an a particle, step by step, looking at the energy required at each step. To do so, we may want to use the following atomic masses: 4He 4.0026 u 12H 2.0141 u 3H 3.01605 u 12H 1.00783 u lp 1.00728 u in 1.00867 u 5.48 x 10-4 u e 1) What is the energy required to remove the first proton? AE 1 = 19.82 MeV Submit Help + 2) Next, what is the energy required to remove the first neutron? ΔΕ2 = MeV Submit + 3) Finally, what is the energy required to separate the remaining neutron and proton? ΔΕ3 = 2.23 Mev Submit + 4) What is the total binding energy of the of the a particle? Ebe = MeV Submit
