Correct choice: "There are eight protons."

Reason: a neutral atom has equal numbers of protons and electrons. If the oxygen atom has 8 electrons, it also has 8 protons (atomic number 8). The number of neutrons can vary by isotope (oxygen‑16 has 8 neutrons, but other isotopes do not). The statements about a charge of ±8 on beryllium are incorrect.
