Which of the following best describes the electrical charge of an electron?

• A. Double negative charge (−2 e)
• B. Negative one elementary charge (−1 e)
• C. Positive one elementary charge (+1 e)
• D. Zero charge (neutral)

Answer: (B)

Verified step by step guidance

1. Recall that the electron is a fundamental subatomic particle with a specific electrical charge.
2. Understand that the elementary charge, denoted as \(e\), is the magnitude of the charge of a proton or electron, where \(e = 1.602 \times 10^{-19}\) coulombs.
3. Recognize that the electron carries a charge equal in magnitude but opposite in sign to the proton's charge.
4. Therefore, the charge of an electron is \(-1\) times the elementary charge, which is written as \(-1 e\).
5. Conclude that the best description of the electron's charge is "Negative one elementary charge (\(-1 e\))".
