អេឡិចត្រុង (Electron)
A glass tube containing a glowing green electron beam
Experiments with a Crookes tube first demonstrated the particle nature of electrons. In this illustration, the profile of the cross-shaped target is projected against the tube face at right by a beam of electrons.[១]

Notes[កែប្រែ]

  1. The fractional version's denominator is the inverse of the decimal value (along with its relative standard uncertainty of ៤,2×10−១៣ u).
  2. The electron's charge is the negative of elementary charge, which has a positive value for the proton.
