Noun[edit] malapropism â(plural malapropisms) (uncountable) The blundering use of an absurdly inappropriate word or expression in place of a similar-sounding one.
Definition of positron. : a positively charged particle having the same mass and magnitude of charge as the electron and constituting the antiparticle of the electron âcalled also antielectron.
Within the limits of experimental accuracy, the electron charge is identical to the charge of a proton, but with the opposite sign. As the symbol e is used for the elementary charge, the electron is commonly symbolized by e â, where the minus sign indicates the negative charge. The positron is symbolized by e + because it has the same properties as the electron but with a positive rather than negative charge. The electron has an intrinsic angular momentum or spin of 1 / 2.
