👉 The term "coelectron" is a quantum mechanical concept in physics that refers to particles with spin and a third state, which are known as spin 1/2 particles. These particles can exist in two states - one being a classical electron-like particle (like an electron) and the other being another type of particle that has no definite nature or identity. The coelectron is a hypothetical quantum state that does not have any definite value or identity, but it can be observed as a result of interactions
