The elementary charge, usually denoted by e, is a fundamental physical constant, defined as the electric charge carried by a single proton or, equivalently, the magnitude of the negative electric charge carried by a single electron, which has charge −1 e.

The elementary charge (the electric charge of the proton) is defined as a fundamental constant in the SI. The value for elementary charge, when expressed in SI units, is exactly 1.602 176 634 × 10 −19 C.
The coulomb (symbol: C) is the unit of electric charge in the International System of Units (SI). It is equal to the electric charge delivered by a 1 ampere current in 1 second and is defined in terms of the elementary charge e, at about 6.241 509 × 10 18 e.
電気素量 （でんきそりょう、 英: elementary charge ）は 電気量 の最小量である。 素電荷 （そでんか）、 電荷素量 とも呼ばれる。 もっぱら記号 e で表される。 電気素量の値は基礎的な 物理定数 であり、 単位 としても用いられる。 現在の値は 電子 1個の運ぶ電気量の大きさとされ、これは 陽子 1個あるいは 陽電子 1個の 電荷 と等しい。 なお クォーク の保持する電気量は電気素量の1/3相当とされるものの、 クォークが単独で現れることはない ため、クオークを支持する立場においても電気素量の値は従来と変わらない。 原子核物理学 や 化学 では粒子の 電荷 を表すために用いられる。
A proton is a positively charged particle located in the nucleus of an atom. An electron has \(\mathrm{\frac{1}{1836}}\) times the mass of a proton, but an equal and opposite negative charge. An elementary charge — that of a proton or electron — is approximately equal to 1.6×10-19Coulombs. Unlike protons, electrons can move from atom to atom.
1 de jan. de 2020 · The elementary charge, e, is one of seven fixed constants defining the International System of Units, the SI, with e = 1.602 176 634 × 10 − 19 C. The elementary charge e corresponds to a coupling strength of the electromagnetic force via the fine-structure constant and is considered as a fundamental constant of nature.
