Which uncharged fundamental particle resides within the nucleus of an atom?
Show answer Hide answer
Answer: B. Neutron
Explanation
Neutrons are neutral subatomic particles with no electric charge in nuclei. They reside within the atomic nucleus alongside positively charged protons. Neutrons contribute significantly to the total mass of atomic isotopes. Subatomic particles include protons, neutrons, and electrons forming all matter. The number of protons determines the chemical element while neutrons vary. Strong nuclear forces bind protons and neutrons tightly together in the center.
Nuclear reactors harness neutron-induced fission to generate electricity. Radioactive dating techniques rely on unstable neutron ratios in atomic isotopes. Chemistry students learn about atomic structure including nuclear particle roles. Electrons carry a negative electric charge and orbit outside the atomic nucleus. Protons possess a positive electric charge and reside within the atomic nucleus. Stating all of above is incorrect because electrons are outside the nucleus.
