Particle Mass Variability

Particle mass variability refers to the differences in mass between constituent particles of substances, even when the number of particles (moles) remains constant, due to the distinct nature of each particle's composition.

Overview

Particle mass variability is a fundamental concept in chemistry that highlights the differences in mass among particles of the same element due to isotopes. Understanding isotopes, atomic mass, and the techniques used to measure these properties, such as mass spectrometry, is crucial for various app...

Key Terms

Isotope
Atoms of the same element with different numbers of neutrons.

Example: Carbon-12 and Carbon-14 are isotopes of carbon.

Atomic Mass
The weighted average mass of an element's isotopes.

Example: The atomic mass of chlorine is approximately 35.5 u.

Mass Spectrometry
A technique used to measure the mass-to-charge ratio of ions.

Example: Mass spectrometry can identify different isotopes in a sample.

Nuclear Reaction
A process in which atomic nuclei interact and change.

Example: Fusion and fission are types of nuclear reactions.

Radiocarbon Dating
A method for determining the age of an object containing organic material.

Example: Radiocarbon dating uses Carbon-14 isotopes.

Mass Defect
The difference between the mass of an atomic nucleus and the sum of its individual nucleons.

Example: Mass defect explains why nuclear binding energy is released.
