The amount of screening of a proton in a metal, migrating under the influence of an applied electric field, is calculated using different theoretical formulations. First the lowest order screening expression derived by Sham [ Phys. Rev. B 12 , 3142 (1975)] is evaluated. Contrary to Sham, ...

been proven wrong with two exceptions–the quark and the quasiparticle). One thing that has never been proven wrong, however, is that the charge is a constant. Regardless of circumstances including things like temperature, pressure and even time, the elementary charge of a proton will not ...
and equivalent to 6.2415 × 1018elementary charges, where one elementary charge is the charge of a proton or the negative of the charge of an electron. A coulomb's value in the International System differs very slightly from that in the meter-kilogram-second-ampere system of units. See Table...
aThe charge of an electron or of a proton is much too small to be basic quantity of charge of charge for almost all practical applications. The SI unit of charge is the coulomb, with the symbol C. A coulomb of negative charge equals that of 6.242(1018 electrons. The coulomb is a deriv...
The important thing to understand about ions is that they are the only types of atom with anet charge. For convenience, chemists (and scientists in general in most cases) take the charge of an electron to be −1, while a proton has a charge of +1. ...
Using semi-local density-functional theory as well as hybrid functionals and embedded correlated wavefunction methods as higher-level benchmarks, we show that the effective charge of a solvated proton in the electrochemical double layer or outer Helmholtz plane at all levels of theory is fractional,...
