Q: Is an electron a subatomic particle? ¶
A: Yes, and symbol e− or β−, whose electric charge is negative one elementary charge.
Q: Are electrons free to transport thermal energy between atoms? ¶
Q: Are electrons quantized? ¶
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 called Compton scattering? ¶
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 a challenging problem of the modern theoretical physics? ¶
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.
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 approximately 9.109×10−31 kilograms? ¶
A: Yes, or 5.489×10−4 atomic mass units.
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 moving relative to an observer it will generate a magnetic field? ¶
Q: Are electrons typically in the range 20–200 eV? ¶
Q: Are electrons identical particles because they cannot be distinguished from each other by their intrinsic physical properties? ¶
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: Is an electron about 1836? ¶
Q: Is an electron incompatible to the premises of the theory of relativity? ¶
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: 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 deflected by a charged particle? ¶
A: Yes, such as a proton.
Q: Are electrons different from the nucleus' electrical charge? ¶
A: Yes, such an atom is called an ion.
Q: Is an electron in motion? ¶
A: Yes, and it generates a magnetic field.
Q: Are electrons distributed in a large volume around nuclei? ¶
Q: Is an electron charged? ¶
A: Yes, and it produces an orbital magnetic moment that is proportional to the angular momentum.
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? ¶
Q: Was an electron bound in space? ¶
A: Yes, for which the electron wave equations did not change in time.
Q: Is an electron a combination of the words electric and ion? ¶
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: Are electrons called Thomson scattering or Linear Thomson scattering? ¶
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 passed through thin metal foils and by American physicists Clinton Davisson and Lester Germer by the reflection of electrons from a crystal of nickel? ¶
Q: Is an electron slightly larger than predicted by Dirac's theory? ¶
Q: Is an electron described by a function called an atomic orbital? ¶
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: Is an electron commonly symbolized by e−? ¶
A: Yes, where the minus sign indicates the negative charge.
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.
