Question

Какое из этих ядер более устойчивое Mg и Zn

Answer 1

Ответ: Mg по моему мнению

Answer 2

Устойчивость ядер резро возрастает с увеличением массы ядра, достигает своего максимума для ядер с Mr = 50--60 а. е. м., а после плавно уменьшается.
Mr (Mg) = 24 а. е. м.
Mr (Zn) = 65 а. е. м.
Поэтому более устойчивым является ядро Zn (попадает в зону, близкую к максимуму устойчивости).

Answer 3

Mg (magnesium) and Zn (zinc) are both chemical elements that belong to the same group in the periodic table, Group 12. While both elements have similar properties, including being metals and having a silvery-white appearance, their stability can be evaluated based on various factors.

The stability of an atomic nucleus is determined by the balance between the strong nuclear force, which holds the nucleus together, and the electrostatic repulsion between protons. One way to assess the stability of a nucleus is by looking at its binding energy per nucleon. The higher the binding energy per nucleon, the more stable the nucleus.

According to available search results, the binding energy per nucleon for Mg is approximately 8.54 MeV However, I couldn't find specific information about the binding energy per nucleon for Zn.

It's important to note that stability can also be influenced by other factors, such as the number of protons and neutrons in the nucleus, the arrangement of nucleons, and the presence of isotopes. Without specific information about the binding energy per nucleon for Zn, it is difficult to make a definitive comparison of the stability between Mg and Zn based solely on this criterion.
