Question

Найдите энергию связи ядра атома бериллия и фтора в Джоулях

Answer 1

Ответ:

масса фтора 18.99840316 а. е. м.

масса протона 1.00727647 а. е. м.

масса нейтрона 1.00866501 а. е. м.

Z=9

N=10

Δm=9*1.00727647+10*1.00866501-18.99840316=0.15373517 а. е. м.

0.15373517 а. е. м. = 2.55283233312e-28 кг

переводим массу в энергию E = mc²

E = 2,55283233312e-28 * 299792458^2 = 2.2943712798383927903651722368e-11 Дж

Answer 2

Energy of Binding between Beryllium and Fluorine Nuclei

The energy of binding between the nuclei of beryllium and fluorine can be calculated based on the nuclear binding energy per nucleon for each element.

The nuclear binding energy per nucleon for beryllium-9 is approximately 6.8 MeV For fluorine-19, the nuclear binding energy per nucleon is approximately 7.7 MeV.

To calculate the energy of binding between the nuclei of beryllium and fluorine, we can use the mass defect and the relationship between mass and energy given by Einstein's mass-energy equivalence principle (E=mc^2).

The mass defect can be calculated by subtracting the total mass of the individual nucleons in the nucleus from the actual measured mass of the nucleus. The mass defect is then used to calculate the binding energy using the relationship E=mc^2.

Using the nuclear binding energy per nucleon values for beryllium and fluorine, the energy of binding between the nuclei of beryllium and fluorine can be determined.

Please note that the exact energy of binding between the nuclei of beryllium and fluorine in joules would require specific calculations based on the mass defect and the mass-energy equivalence principle.
