Which one indicates the correct types of charge for electrons and protons?

Question

BlackTom AI · Accepted Answer

The question asks: Which option indicates the correct types of charge for electrons and protons?
Option a: 'Electrons are negative charges, protons are positive charges' — This is the correct description according to established atomic theory: electrons carry a negative electric charge, while protons carry a positive electric charge, and they align with the fundamental charges used in chemistry and physics.
Option b: 'Electrons are negative charges, protons are neutral charges' — This is incorrect because protons are not neutral; they carry a positive charge, so describing protons as neutral contradicts the well-supported charge of a proton.
Option c: 'Electrons are positive charges, protons are negative charges' — This reverses the actual charges and would invert many physical phenomena, making this option false.
Option d: 'Electrons are neutral charges, protons are positive charges' — Electrons are not neutral; they have a distinct negative charge, so this statement mislabels the electron’s charge and is incorrect.
In summary, only option a correctly states the charges of both particles, while the other options assign incorrect charges to either electrons, protons, or both.
