/ˈbaɪndɪŋ ˈɛnərdʒi/C1formalscientific
  • ruЭнергия, необходимая для разделения системы на составные части, или энергия, выделяющаяся при образовании системы из её компонентов. В физике обычно относится к энергии, удерживающей атомное ядро вместе, или к энергии, связывающей электроны с атомом.

The energy required to separate a system into its constituent parts, or the energy released when a system is formed from its components. In physics, it commonly refers to the energy holding an atomic nucleus together or the energy that binds electrons to an atom.

  1. Nuclear binding energyC2formal

    The energy required to disassemble a nucleus into its constituent protons and neutrons, or the energy released when a nucleus is formed from these particles.

    • The binding energy of a helium nucleus is about 28.3 MeV.
    • Nuclear fission releases energy because the binding energy per nucleon of the products is higher.
    • Scientists measure binding energy to understand nuclear stability.
  2. Molecular binding energyC2formal

    The energy released when atoms or molecules bond together, or the energy required to break that bond.

    • The binding energy of a hydrogen molecule is 4.52 eV.
    • High binding energy indicates a strong chemical bond.
    • Calculating binding energy helps predict molecular stability.
