(a) Explain why hydrogen H 1 1 (proton) cannot appear on the graph shown in Figure.

Nucleus of hydrogen has only one proton. Hence its binding energy will be zero . The nuclear binding energy is the energy it takes to separate all the nucleons in a nucleus from each other. Since there is only the one nucleon, it's already separated from any other nucleons. Therefore, hydrogen is not shown in the given graph.

The mass of a 4 8 Be nucleus is 1 . 33 × 10 - 26 kg . For the nucleus of Be 4 8 , determine: (a) the mass defect in $\mathrm{kg}$

Using the given values in book we have, M a s s d e f e c t Δ m = 4 m p + 4 m n – m B e ⇒ ∆ m ≈ ( 8 × 1 . 67 – 13 . 3 ) × 10 - 27 ⇒ ∆ m = 6 . 00 × 10 - 29 kg

The mass of a 4 8 Be nucleus is 1 . 33 × 10 - 26 kg . For the nucleus of Be 4 8 , determine: (b) the binding energy of the nucleus in $\mathrm{MeV}$

Using the given values in book we have, M a s s d e f e c t Δ m = 4 m p + 4 m n – m B e ⇒ ∆ m ≈ ( 8 × 1 . 67 – 13 . 3 ) × 10 - 27 ⇒ ∆ m = 6 . 00 × 10 - 29 kg Now, B i n d i n g e n e r g y E B = Δ m c 2 ⇒ E B = 6 . 00 × 10 - 29 × ( 3 . 00 × 10 8 ) 2 ⇒ E B = 5 . 4 × 10 - 12 J ⇒ E B = 5 . 4 × 10 - 12 1 . 6 × 10 - 19 e V = 3 . 4 × 10 7 e V ⇒ E B = 34 Mev

The mass of a 4 8 Be nucleus is 1 . 33 × 10 - 26 kg . For the nucleus of Be 4 8 , determine: (c) the binding energy (in $\mathrm{MeV}$ ) per nucleon for the nucleus.

Using the given values in book we have, M a s s d e f e c t Δ m = 4 m p + 4 m n – m B e ⇒ ∆ m ≈ ( 8 × 1 . 67 – 13 . 3 ) × 10 - 27 ⇒ ∆ m = 6 . 00 × 10 - 29 kg Now, B i n d i n g e n e r g y E B = Δ m c 2 ⇒ E B = 6 . 00 × 10 - 29 × ( 3 . 00 × 10 8 ) 2 ⇒ E B = 5 . 4 × 10 - 12 J ⇒ E B = 5 . 4 × 10 - 12 1 . 6 × 10 - 19 e V = 3 . 4 × 10 7 e V ⇒ E B = 34 Mev Since there are total 8 nucleons therefore, B i n d i n g e n e r g y p e r n u c l e o n = E B n ⇒ E B n = 34 Mev 8 = 4 . 25 Mev
