# What is the charge of a single electron?

Jun 9, 2018

#### Answer:

One electron holds a negative charge of 1-

#### Explanation:

In an atom, the protons hold a positive charge, the neutrons a neutral charge and the electrons a negative charge. So long as it is not an ion, the charge of this atom will always be 0 overall, with the same amount of protons as electrons. So one singular electron with no proton to balance it out must have a negative charge equivalent to the number of electrons more than protons. Thus the overall charge must be 1-.

#### Answer:

$- 1$

#### Explanation:

An electron has a charge of $- 1$. In terms of coulombs, it is just the negative version of the elementary charge $e$.

A charge of an electron in coulombs is approximately equal to:

${e}^{-} = - 1.6 \cdot {10}^{-} 19 \setminus \text{C}$
