question 87

Multiple Choice

Which of the effects listed below is not a major effect influencing the binding energy of the nucleus in the liquid-drop model?

• A) The volume effect: the binding energy per nucleon is approximately constant when A > 50.
• B) The surface effect: nucleons in the surface have fewer neighbors.
• C) The quantum number effect: all nucleons in the nucleus have the same set of quantum numbers.
• D) The Coulomb repulsion effect: protons repel protons.
• E) The symmetry effect: stable nuclei tend to have N ≈ Z.

Definitions:

Peaks

Points on a graph, often seen in spectroscopy or chromatography, representing the maximum intensity or concentration of a component within a sample.

Spectral Data

Information obtained from measuring the interaction of electromagnetic radiation with matter, typically used in analysis of chemical properties.

Triplet

A splitting pattern in NMR spectroscopy, where a peak is divided into three distinct components, often due to two equivalent neighboring nuclei.

IR

Infrared spectroscopy, a technique used to identify and study chemicals through the interaction of infrared radiation with molecular vibrations.
