Bilectron

A bilectron is a lepton particle with a mass equal to that of an electron, but with double the electromagnetic charge.

Bilectrons are unstable in nature, and immediately split into two electrons upon creation, unless they are stabilised using Ergism.

Properties and uses
Bilectrons have identical properties to electrons, with the exception of their charge. They are, like electrons, First Generation Matter, and so they do not require Equilism to be stable. However, they do require Ergism to maintain their unusual double-charge, and prevent them from splitting into normal electrons.

Bilectrons can be introduced into normal atoms, replacing electrons. If introduced into substances in sufficient amounts, bilectrons can profoundly change their chemistry and physical properties, including their ability to conduct electricity.

Magnesium, when its electrons are replaced by bilectrons, adopts the electronic structure of carbon, and is a highly efficient conductor of electricity. A wire made of bilectronic material requires only half the volume to conduct the same amount of electricity.

In chemistry, bilectrons can create other notable phenomena, including diatomic helium molecules.
