Many subatomic particles, including the electrically charged electron and proton and the electrically neutral neutron, behave like elementary magnets.
The more massive members of each lepton pair are the electrically charged electron (the outer constituent of atoms) and two other particles that resemble electrons in all measurable ways except that they are heavier, and are unstable in today's modern universe.The remaining five particles in the model are called bosons (after Satyendranath Bose, an Indian physicist who collaborated with Einstein).
The universe's primordial photons, which had previously been scattering chaotically off the electrically charged protons, electrons and alpha particles now imprisoned in the newly formed atoms, were thereby set free.
But the effect of the neutral current the passage of a virtual Z0 between the antineutrino and the electron would set the electron in motion, and, being electrically charged, the electron would leave a track, which would appear as if from nowhere.
The trap E1 is electrically charged upon electron emission, and it becomes neutral by capturing an electron.
His nine employees circled him like charged electrons.
The results of experimentation presented a seemingly irrefutable picture of the atom: tiny electrically charged particles called electrons continuously moving in circles around an oppositely charged and extraordinarily dense nucleus.
By that point, electrically charged protons and electrons had slowed down enough to coalesce into neutral atoms of hydrogen, which formed the seeds of large-scale cosmic structures like galaxy clusters.
Dehmelt received his share of the prize for his development of the Penning trap, an electromagnetic device that can hold small numbers of ions (electrically charged atoms) and electrons for periods of time long enough to allow their properties to be studied with unprecedented accuracy.
In descending order of strength, they are: gravity which pulls matter together; electromagnetic which attracts and repels electrically charged particles (like electrons or nuclei); and the strong and weak nuclear forces which hold the nuclei of atoms themselves together.
