How is the charge of a proton related to the charge of an electron?

• A. The proton has a charge equal in magnitude but opposite in sign to the electron.
• B. The proton has twice the charge of the electron.
• C. The proton and electron have charges of the same sign and magnitude.
• D. The proton has no charge, while the electron is negatively charged.

Answer: (A)

Verified step by step guidance

1. Recall that the charge of subatomic particles is a fundamental property in chemistry and physics.
2. Understand that the electron carries a negative charge, which is conventionally taken as -1 elementary charge (\(-1e\)).
3. Know that the proton carries a positive charge, which is equal in magnitude but opposite in sign to the electron's charge (\(+1e\)).
4. Recognize that the magnitude of the charge on a proton and an electron is the same, but their signs differ, making them opposite charges.
5. Therefore, the correct relationship is that the proton has a charge equal in magnitude but opposite in sign to the electron.
