Electron FAQs:


Q: Is an electron a subatomic particle?

A: Yes, and symbol e− or β−, with a negative elementary electric charge.

Q: Are electrons free to transport thermal energy between atoms?

A: Yes.

Q: Is an electron deflected by a charged particle?

A: Yes, such as a proton.

Q: Is an electron charged?

A: Yes, and it produces an orbital magnetic moment that is proportional to the angular momentum.

Q: Is an electron moving relative to an observer it will generate a magnetic field?

A: Yes.

Q: Are electrons easier to observe with experiments than those of other particles like neutrons and protons because electrons have a lower mass and hence a longer De Broglie wavelength for a given energy?

A: Yes.

Q: Are electrons called Thomson scattering or Linear Thomson scattering?

A: Yes.

Q: Are electrons involved in many applications such as electronics?

A: Yes, and welding, cathode ray tubes, electron microscopes, radiation therapy, lasers, gaseous ionization detectors and particle accelerators.

Q: Are electrons swapped?

A: Yes, that is, ψ = −ψ , where the variables r1 and r2 correspond to the first and second electrons, respectively.

Q: Are electrons not associated with specific atoms?

A: Yes, so when an electric field is applied, they are free to move like a gas through the material much like free electrons.

Q: Is an electron about 1836?

A: Yes.

Q: Is an electron the least massive particle with non-zero electric charge?

A: Yes, so its decay would violate charge conservation.

Q: Is an electron actually smaller than its true value?

A: Yes, and the charge decreases with increasing distance from the electron.

Q: Is an electron a challenging problem of the modern theoretical physics?

A: Yes.

Q: Is an electron called Compton scattering?

A: Yes.

Q: Were electrons describable?

A: Yes, and quantum mechanics made it possible to predict the configuration of electrons in atoms with atomic numbers greater than hydrogen.

Q: Is an electron called the positron?

A: Yes, it is identical to the electron except that it carries electrical and other charges of the opposite sign.

Q: Is an electron a combination of the words electric and ion?

A: Yes.

Q: Was an electron measured to a precision of eleven digits?

A: Yes, and which, in 1980, was a greater accuracy than for any other physical constant.

Q: Is an electron commonly symbolized by e−?

A: Yes, where the minus sign indicates the negative charge.

Q: Is an electron in motion?

A: Yes, and it generates a magnetic field.

Q: Is an electron described by a function called an atomic orbital?

A: Yes.

Q: Are electrons quantized?

A: Yes.

Q: Is an electron approximately 9.109×10−31 kilograms?

A: Yes, or 5.489×10−4 atomic mass units.

Q: Is an electron moving through a magnetic field?

A: Yes, and it is subject to the Lorentz force that acts perpendicularly to the plane defined by the magnetic field and the electron velocity.

Q: Are electrons identical particles because they cannot be distinguished from each other by their intrinsic physical properties?

A: Yes.

Q: Are electrons different from the nucleus' electrical charge?

A: Yes, such an atom is called an ion.

Q: Are electrons important in cathode ray tubes?

A: Yes, and which have been extensively used as display devices in laboratory instruments, computer monitors and television sets.

Q: Was an electron bound in space?

A: Yes, for which the electron wave equations did not change in time.

Q: Is an electron incompatible to the premises of the theory of relativity?

A: Yes.

Q: Is an electron slightly larger than predicted by Dirac's theory?

A: Yes.

Q: Are electrons distributed in a large volume around nuclei?

A: Yes.

Q: Was an electron again proposed for these particles by the Irish physicist George Johnstone Stoney?

A: Yes, and the name has since gained universal acceptance.

Q: Are electrons typically in the range 20–200 eV?

A: Yes.

Q: Are electrons passed through thin metal foils and by American physicists Clinton Davisson and Lester Germer by the reflection of electrons from a crystal of nickel?

A: Yes.

Q: Were electrons distributed in successive "concentric spherical shells, all of equal thickness"?

A: Yes, In turn, he divided the shells into a number of cells each of which contained one pair of electrons.
