Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
A stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.
- ‘It exists when the electrons of the atom are occupying the orbitals of lowest energy.’
- ‘It was the antiparticle to the electron, later called the positron.’
- ‘The ionization energy is the energy needed to remove an electron from a gaseous atom.’
- ‘At the time, it was believed that electrons colliding with atoms always lost energy.’
- ‘It was like looking at the evenly spaced energy levels of electrons in an atom.’
- ‘At that stage, the electrons and ions combined into neutral atoms that no longer scattered the radiation.’
- ‘Nucleons like to pair up and form a shell structure, just as electrons do in atoms.’
- ‘This means that an atom with eight electrons in its outermost energy level is very stable.’
- ‘It was soon discovered that the proton, the neutron, and the electron are not alone.’
- ‘The outer shell of an oxygen atom holds six outer electrons, though it has room for eight.’
- ‘This species substitutes for a proton on an electron rich carbon in the benzene ring.’
- ‘Electric current is the movement of electrons from one atom to another in a conductor.’
- ‘If this attraction is strong enough, it will pull the electrons free from the atoms.’
- ‘Like the Solar Wind, the magnetosphere is full of plasma, consisting of ions and electrons.’
- ‘If the star were squeezed even more by gravity, the electrons could be forced to combine with protons to make more neutrons.’
- ‘For example, two electrons in an atom may differ in orbital angular momentum or in spin direction.’
- ‘The electron and muon neutrinos are easier to produce and detect than the tau neutrino.’
- ‘Chemical reactions inside the cell strip electrons from the hydrogen atoms to produce a voltage that can power a circuit.’
- ‘The antiparticle of the electron is the positron; there are also antiquarks and antineutrinos.’
- ‘Most beta decays involve the emission of electrons from the nucleus as a neutron decays into an electron and a proton.’
Late 19th century: from electric + -on.
