noun
Definition

A property in quantum physics that describes the behavior of certain subatomic particles, indicating how they can exist in different charge states, similar to how spin describes their angular momentum.


Example

In particle physics, isospin helps to explain the similarities between protons and neutrons.

Root Explanation

Isospin is formed from "iso-" (meaning equal) and "spin" (from the concept of angular momentum in physics). The term describes a symmetry in particle physics where particles are treated as if they have the same mass and are interchangeable, akin to having equal spin properties.

Memory Tip

Think of 'equal' ('iso-') properties in 'spin' to remember that isospin refers to a symmetry in particle physics where particles behave similarly.
