Electron

There is one electron in a hydrogen atom.

Cooper pairs are electron pairs formed in superconductors.

An hydrogen atom only has one proton and one electron.

The atom's nucleus is surrounded by an electron cloud.

The nucleus of a hydrogen atom consists of a single proton. Around this proton orbits a single electron.

A positron is a small particle similar to an electron, but with a positive electric charge.

I've never been able to wrap my brain around the electron configuration for chromium.

The electron shell is full.

This instrument is what’s known as a Faraday cup, a sensor designed to measure the ion and electron fluxes and flow angles from the solar wind.

The electron is an elementary particle.
