2. The positron or antielectron is the particle with an electric charge of +1 e, a spin of 1/2 (the same as the electron), and the same mass as an electron. It is the antiparticle ( antimatter counterpart) of the electron. When a positron collides with an electron, annihilation occurs. If this collision occurs at low energies, it results in the ...

基本电荷. 基本電荷 （符號： ，也稱 元電荷 ），是一個 質子 所帶的 電荷 量，或一個 電子 所帶的負電荷的量。. 為了避免其符號造成混淆， 有時候會被稱為 基本正電荷 （ elementary positive charge ）。. 它是一個基本 物理常數 ，是 原子單位 和一些其它 自然單位 ...
6 apr 2018 · Mark Keller explains how the elementary charge will soon be reinstated in metrology — and why it got sidelined in the first place.
Carga elementar. A carga elementar é aquela carga elétrica transportada por um único próton ou, de maneira equivalente em módulo, por um único elétron. Ela é exatamente 1,602 176 634 × 10 -19 C [ 1] e, convencionalmente se utiliza as letras e ou qe para denotá-la.
La carica elettrica è la carica fisica responsabile dell' interazione elettromagnetica e sorgente del campo elettromagnetico. La sua unità di misura nel Sistema internazionale è il coulomb ( ) [1]. È una grandezza scalare, dotata di segno e quantizzata, ossia (con l'eccezione dei quark) può assumere solo valori multipli di una quantità ...
Electronvolt. In physics, an electronvolt (symbol eV ), also written electron-volt and electron volt, is the measure of an amount of kinetic energy gained by a single electron accelerating through an electric potential difference of one volt in vacuum. When used as a unit of energy, the numerical value of 1 eV in joules (symbol J) is equal to ...
