Which subatomic particles are positively charged?

  1. Neutrons

  2. Electrons

  3. Atoms

  4. Protons

The correct answer is: Protons

Protons are the subatomic particles that carry a positive charge. They are found in the nucleus of an atom and are one of the primary constituents of atomic structure. Their positive charge is essential for the stability of atoms, as they attract negatively charged electrons, which orbit the nucleus. This interaction between protons and electrons is fundamental to the formation of atoms and, consequently, the molecules that make up matter. The other particles mentioned do not have a positive charge. Neutrons are neutral, meaning they carry no charge at all, while electrons are negatively charged. Atoms themselves are not classified by charge in the same way subatomic particles are; they can be neutral or charged depending on the balance between protons and electrons. However, the presence of protons is what contributes to the overall positive charge in cases where there are more protons than electrons.
