What particle carries a positive charge in an atom?

Neutron
Proton
Electron
Positron

The correct answer is: Proton

A neutron does not carry any charge, hence it is incorrect. An electron carries a negative charge and is found in the electron cloud around the nucleus, it is not contained in the nucleus. A positron has the same mass as an electron but has a positive charge, however it is not found in a regular atom and is often produced during radioactive decay. A proton, on the other hand, carries a positive charge and is found in the nucleus of an atom. Protons and neutrons are collectively known as nucleons and make up the majority of the mass of an atom. In a neutral atom, the number of protons is equal to the number of electrons, balancing out the positive and negative charges and creating a stable atom. Therefore, the correct answer is B.
