    Vor 2 Tagen · Electrons have an electric charge of −1.602 176 634 × 10 −19 coulombs, which is used as a standard unit of charge for subatomic particles, and is also called the elementary charge. Within the limits of experimental accuracy, the electron charge is identical to the charge of a proton, but with the opposite sign. [80]

    Vor einem Tag · A photon (from Ancient Greek φῶς, φωτός (phôs, phōtós) 'light') is an elementary particle that is a quantum of the electromagnetic field, including electromagnetic radiation such as light and radio waves, and the force carrier for the electromagnetic force. Photons are massless particles that always move at the speed of light when in vacuum.

  4. Vor 4 Tagen · One of the most basic principle that many people fail to understand is the quantization of charges, according to which a charge can only be an integer multiple of the elementary charge \(e = 1.6\times 10^{-19}\text{C}\). Mathematically, we can say

    Vor 2 Tagen · The electron configuration is determined by the charge of the nucleus, which is determined by the number of protons, or atomic number. The number of neutrons is the neutron number. Neutrons do not affect the electron configuration. Atoms of a chemical element that differ only in neutron number are called isotopes.

    Vor 2 Tagen · Eisen ist ein chemisches Element mit dem Symbol Fe ( lateinisch ferrum ‚Eisen‘) und der Ordnungszahl 26. Es gehört zu den Übergangsmetallen, die im Periodensystem die 8. Nebengruppe ( Eisen-Platin-Gruppe ), nach der neuen Zählung die Gruppe 8 ( Eisengruppe) bilden. Eisen ist, auf den Massenanteil ( ppmw) bezogen, nach Sauerstoff ...
