Question

Quizplus · Accepted Answer

Atoms are composed of a nucleus with positively charged protons and neutral neutrons, orbited by negatively charged electrons. Atoms are electrically neutral because the number of protons (which carry positive charge) equals the number of electrons (which carry negative charge). Isotopes are variants of the same element with differing numbers of neutrons, ions are atoms or molecules with a net electric charge due to the loss or gain of electrons, and electrons and protons are subatomic particles that make up atoms.
